You fear we might lose Diego to Inter?
I fear that too. As i said many times, Diego is like the only player Inter are missing to make the step from perennial losers in Europe to a team worthy of a semifinal, final, winner of CL.
Stankovic, even though a grateful hard worker that is having a good season, isn't a good link between the midfield and the attackers and that's why Maicon has to create the chances or Ibra has to do everything by himself. With Diego in the team (only one single new player), you suddenly get a much stronger and more dangerous team. Diego can do (attacking wise) everything better than Stankovic. He will pass better, assist more, score more.
I'd be really surprised if Inter don't go after Diego. If i was in Mourinho's place i'd tell Moratti to pay as much as it takes to get the guy.
