The players themselves need to be edited/modded to look like the character they're portraying, that was really lame to have players that had nothing special about them.
Two commentators. Not more than that (well, three can work but the issue is chemistry, it's easier to ensure it's kept fine when there's two of them). And they need to be serious about it, actually involved in the game, and to know the names of the players and even if possible a bit of the "board culture". At least one of the two needs to know his shit about football/soccer
