Diego Forlan says Atletico Madrid should sell teammate Sergio Aguero.

Aguero has declared he wants to leave Atletico this summer, with Real Madrid, Manchester City and Chelsea all keen.

"He said he wasn't going to stay and his statement is there [for all to see]," he said.

"It's a shame because he is an important player; the two of us knew each other well and we formed a very good partnership, but I'm not going to analyse it and say if it is right or wrong - if he is really happy with the decision he made, then we have to accept it and wish him good luck."
