Konami's detailed the first free DLC content for PES 2010 on PS3, Xbox 360 and PC.
The DLC, which will be released on November 24, "enhances a number of elements in the full game and also revises the club team rosters in line with those of all current transfers," says Konami.
Furthermore, four new teams will be added to PES 2010's UEFA Champions League mode, with Atletico Madrid, Olympiacos, Lyon and Fiorentina all added to the competition in their official Champions League kits.
Similarly, the DLC will also update the home kit of the Japanese national team, which was recently changed, Konami notes.
A 'primer update' is available to download now, it says, and will ready the relevant hardware for the full DLC update which will be released on November 24th.
"The initial download will ensure that any PES 2010 Edit data the user has stored on their hardware will not be affected by future Konami DLC," it says.
The publisher notes it's "committed" to releasing further PES updates and will be working with the community to decide where the game can be improved.
