AC Milan striker Alexandre Pato expects to return after the international break.
Pato has stated that Sunday's clash with Catania has come too soon.
"When I was hurt I also spoke with the doctor of the Brazilian national team and he confirmed this injury would need four to six weeks.
"Six weeks have just passed, I am ready, but it is impossible to play against Catania because I have not trained with the team. I will be back after the [international] break."
