Master League has proven one of the key attributes to the PES series longevity, and PES 2010 will introduce a number of new elements that will contribute to the overall realism and lasting appeal of the new game.On selecting the Master League option, players are now presented with a menu split into three areas: Club House, Stadium Walk, and Office. Each of these is an umbrella for different parts of a manager's role, with Club House used for tactical and match day options, Stadium Walk for main game settings, and office for scouting and player acquisition dealings.The in-game menus are now much simpler to navigate, and players can jump between the three areas with ease. The Club House element has also seen the creation of an all-new Youth Team section, which works alongside the first team squad. As the game progresses, the player can opt to invest in talented members of their youth team to fast-track their development. This burgeoning talent can then be introduced into the first team, as with so many real-life academies.The Office area is where all transfer and financial dealings take place. Real currency is now used in PES 2010, and additional monetary routes are also available. Sponsorships can now be negotiated, with player securing big money deals with companies that can be used to invest in the team and youth set-up. Results on field affect the direct value of the club tio interested parties, and fan clubs are also used as a barometer of the club's success.
