I'd like him to stay. He's so useful, we can use him almost anywhere on the pitch. But we should definitely look into the reasons why he gets injured so often.
Everytime Adriano stretches to latch onto a long ball, he pulls his hamstring...Is he simply not stretching properly or is this a chronic issue ala Jeffren
If the initial prognosis was correct we could see Adriano back for return leg vs. PSG. He's probably the best choice for DC since Puyol and Mascherano are out.
