Inter Africa
If the metric is how many African players are on the pitch, then your team in the 2010 UEFA Champions League final is Inter Milan.

If the choice of which team to root for in the 22 May 2010 UEFA Champions League final was based on how many African players they fielded, then apparently, you should root for Inter Milan. Milan has three African players on its roster: Samuel Eto’o, Sulley Muntari, and McDonald Mariga. That’s, of course, if Muntari and Mariga get to play.
In contrast, Bayern Munich has zero African players in its team, argues Piers Edwards in his football blog on the BBC’s site. Edwards adds: “ . . . As excitement mounts across Africa about the looming World Cup, the European final should be the perfect curtain-raiser for the big one and affords Muntari and Mariga the chance to join the select group of Africans to have won the trophy – Bruce Grobbelaar, Abedi Pele, Rabah Madjer, Sammy Kuffuor, Kanu and Djimi Traore prominent amongst them . . . ”

Milan manager, Jose Mourinho, has a history of trusting African players (even if he inherited them from a previous manager) in key positions–think Benni McCarthy at Porto or Didier Drogba, Michael Essien, and John Mikel Obi at Chelsea.
