Beckham can play in the Pirlo role or next to Kaka behind a single striker ... or soemtimes even in Gattuso's role to provide more attacking quality vs certain teams now that we have Oddo at RB, who is pretty sollid in defense.
of course we could always use him as a Right wing if necessary.
there are plenty of roles he could be useful ... and that's in the short run of ocurse as he is a no long-term investment ... plus, it's not like he is gonna be an automatiuc starter.
Plus he would be available for free, so it's not like we would be putting much money into him.
Most imporantly, however, he is big game player and could be useful with his experience and ball-distibution in CL games.
Like him or not the guy has his qualities and the makeover his presence gave to Real M and England NT is testamant for that ... such players can always be useful even if at first it seems he won't fit to Milan's system, and that's exactly what Carlo's approach to quality players is, and he said it in gazzetta - "bring them in and after that I will worry about where to play them"
of course getting a younger player would probably be better for the team, with future in mind, but I won't lose sleep if Milan decides to bring in a 30+ yo Beckham or Emerson.
