Below is a list of trivial information that have occured during the series' history.
 Wrong Club
 PES 4
- Former Ajax defender Hatem Trabelsi was in the Arsenal roster in PES4 despite never actually signing for the club. He was only on trial there during the Summer of 2004.
 PES 2008
 PES 2009
- Players such as Rafael Sobis, Rivaldo, Ariel Ortega and Ricardinho were playing for their previous clubs in PES 2009 despite playing for clubs that aren't in the game.
 Spelling Errors
- West Ham's John Paintsil has his name down as Pantsil. Although this is due to a Home Office error, where they registered him as Pantsil for his work permit in 2006. The game player can accurately change this by changing his player name to the correct spelling of Paintsil, but his Name on Shirt option to Pantsil to reflect life.
- Florin Cernat's surname is wrongly spelled as Chernat.
- Rodrigo Possebon's surname is wrongly spelled as Possebom.
- Claudio Pizarro's surname is wrongly spelled as Pizzaro.

- Jakub Blaszczykowski's surname is wrongly spelled as Braszczykowski.
- Lee Cattermole's surname is wrongly spelled as Catermole.
- Azar Karadas' surname is wrongly spelled as Kardas.
- Javier Garrido is wrongly spelled Jabier Garrido.
- Oliver Kahn was named Kalm as a result of Kahn holding the rights to his image.

- Franck Dja Djedje's surname is wrongly spelled Djadjedje.
- Cesar Villaluz is wrongly known as C. Martínez, his mother's surname.

- Alhassane Keita Otchico is wrongly spelled Kta. Otchico.

 PES 2010

 PES 2011
- Blaise Nkufo is wrongly spelt N'Kufo
 Wrong Age
 PES 4
- A lot of South American internationals on PES 4, mainly those whose clubs aren't on the game, were put as being 20 years old. This meant some top class players like Paraguay's Jose Cardozo, Argentina's Claudio Lopez and Pablo Cavallero and Brazil's Marcos became firm favourites with Master League players alike due to their impressive stats and young age.
- Paul Jones in PES 4 was put as age 17.
 PES 2011
- Marcelinho from Sao Paulo was put as age 18 despite being 35 in real life
 Incorrrect Skin Colour
 PES 4
- On PES 4, former Chelsea goalkeeper Yves Makabu Ma-Kalambay was portrayed as a Caucasian man, when he is in fact black and of Congolese decent. On the same game, Anthony Vanden Borre was given skin colour 1 when it's in fact closer to 3, this was fixed since then. Similarly Trinidad and Tobago international Carlos Edwards is portrayed as a white player for no apparent reason along with the Brazilian preset faced footballer Cesar Aparecido Rodrigues and Brazilian-born Poland international Roger Guerreiro. Lastly, Danny Simpson's skin tone appears to be too light as he should at least be a skin tone 3.
- Sören Colding is another victim of being portrayed as dark-skinned. It is more closer to one.
- In older versions of PES, Luis Hernandez of Mexico was portrayed as brown skinned, he is in fact Caucasian.
- In previous PES games Lucho Gonzalez, Milan Baros, Helder Postiga and Yossi Benayoun were among the many high profile players given a dark skin tone despite being caucasian before the introduction of preset faces for those particular players.
 PES 2008
- Luke Young is displayed as having skin type 3, despite the fact he has a white skin tone. (this mistake is still on-going)
- Cicinho, a Brazilian of Italian origin is also a victim of having the skin type 3.
- Similarly Salva Ballesta, Sergio Romero, Matias Silvestre, Ricardinho, Gustavo Munua, Nilmar, Edu Dracena, Reimond Manco, Oscar Cardozo (earlier versions), Banel Nicolita, Mauro Rosales, Ersen Martin and Sebastian Giovinco (fixed in PES 2009) are portrayed as black in PES 2008 despite being caucasian. Also Juan Roman Riquelme (earlier versions), Eduardo, Nuno Gomes (earlier versions), Carlos Tevez and Ricardo Quaresma appear to be too dark in Pro Evo games. Even though Fellipe Bastos doesn't have a preset face, he is made too dark.
 Super Cruyff
- Classic Netherlands striker Johann Cruyff is able to occupy every outfield playing position available in PES 2008.
 Nationality Errors
- Occasionally, the producers of Pro Evolution Soccer make mistakes concerning the nationalities of some players. This may be due to the player being eligible for more than one nation, and having not picked a country before the release date of the game.
Examples of players being registered to the wrong nation are:
- Ivan Rakitic (Born in Switzerland and played for the Swiss U-21 team before choosing the Croatian national team, registered under Switzerland).
- Hernan Dellafiore (Argentinian born but represented Italy at youth level, registered under Argentina).
- Pepe (Born in Brazil, but chose to represent Portugal at international level, registered under Brazil).
- Fellipe Bastos has been classed as Portuguese despite being Brazilian.
- Jeffren is registered as Venezuelan although he represented Spain at youth level.
- Liedson Muniz is born in Brazil but represented Portugal at senior level, is registered as a Brazilian
 Bonus GK Ability
- Throughout the game most outfield players have the GK skills of 50 or in the case of blank players (Player 001, 002 etc.), 60. However, Konami have decided that if a outfield player is forced to play in goal due to an injury to their Goalkeeper, their attribute will be increased to 55 or 60 instead.
 Default Team Name Change
- After Pro Evolution Soccer 2 the Master League Defaults had a huge name upheaval, as all players recieved a small alteration to their names.
These changes were as simple as the changing of one letter, such as the change of playmaker Miranda to Minanda.
 Secret/Bonus Stats for Japan
- According to some Winning Eleven fans from Japan, they claim that Goalkeepers on the game have some additional stats. These stats comprise of abilities such as throwing speed and distance amongst others. These stats were visible in formation settings on the PS2 games outside of Japan.
 Replays = Goals?
- On PES4, if you pressed pause when the ball just crossed the line and chose replay, you would get an additional goal for each replay.
 Missing Players
 PES 2009
- Players such as Eidur Gudjohnsen, Dudu Cearense and Robbie Fowler were missing from the original edition of PES 2009 however they were added after the patch with preset faces.
- On the other hand some players such as Danny Alves, Keith Andrews, Walter Lopez and Diego Tristan were still absent from the game much to the disgust of players. This was corrected in the February update.
- Albert Riera is also missing for PS2 users along with Asier Del Horno and Louis Saha.
 Licensed Kit Errors
 PES 3
- South Korea's kits in PES3 were missing the Nike swoosh although Juventus had it on their kits on the game.
 PES 6
- Most Ligue 1 in PES6 where all teams bar Paris Saint-Germain and RC Lens, the only French teams manufactured by Nike, were all given similar grey 'keeper uniforms.
 PES 2009
- ADO Den Haag and Slavia Prague have also been been given grey goalkeeper kits, though including club emblem and sponsors but not kit manufacturer.
- Liverpool's away Premier League font in PES 2009 should have been white with a black outline opposed to red with a black outline. Another error is that the red font is supposed to have a white outline.
- Ajax is missing two stars above the crest on their jerseys which PSV and Feyenoord manage to have.
- France were given their old home kit on PES 2009, which changed straight after the European Championships. This was fixed in the November update.
- The following teams have their sponsors missing thoughout the series (sponsors in brackets):
- CFR Cluj (Sigma Towers - PES 2009)
- Celtic & Rangers (Carling - This is due to alcohol advertising on a game with a 3+ age rating or E for Everyone rating and such advertising being banned in territories such as France, Norway and the United States. Both teams had their sponsor in PES5 though)
- FC Copenhagen (Carlsberg - Alcohol advertising. Liverpool have the same sponsor but seem to be exempt from this)
- Udinese (Lotto - PES 2009 - Already features on the kit due to them being their kit manufacturers. Sponsor later unveiled to be Dacia)
- RCD Mallorca (Illes Ballears - PES 2009)
- Bayern Munich (T-Home - PES 2008)
- FC Barcelona (Unicef - PES 6 - This was because the season was well underway when they acquired it)
- Sevilla (888.com - PES 6)
 Licensed English League?
- In the Japanese version of PES 4, it is said that the Barclays Premier League (or at least Blackburn Rovers) is licensed in the PES 4 Japanese Version.
 Wrong Foot
- Fabio da Silva is wrongly portrayed as a left footed player despite being right footed.
