Konami announced the release of a free ADDITIONAL content for PES 2015 to today. This data pack includes the integration of four new teams, new models of 73 players and 4 new stadiums but also many features and updates are made to myClub mode.

Konami Digital Entertainment B.V. today announced that the greatest Pro Evolution Soccer 2015 players from around the globe will gather at UEFA Festival as the grand final of the PES World Finals is held mere hours before the UEFA Champions League Final on June 6th.

Konami:
The free Data Pack 4 will be released globally on March 12. This update includes the latest rosters across all modes in the game, improves a number of player likenesses, adds new stadia and kits, and implements the latest boots and balls from a number of key suppliers.
very generous pack, cheers konami, pretty much changed all the boots, and added some nice new football styles
FINALLY! I'm pretty much done with MyClub this year, 700 plus ranking D3 (not to brag=p). And I've been waiting for a proper update so that I can start my ML!

Roster update, new stadium, boots, balls and visual upgrades incoming.
I hope they have made the CPU a bit more aggressive, cause they rarely foul you, meaning you almost never get a free kick.
