AC Milan coach Massimiliano Allegri admits its going to be a difficult week with so many veterans leaving.

Alessandro Nesta, Gennaro Gattuso, Pippo Inzaghi and Mark van Bommel have all confirmed they are leaving Milan.

"These are going to be difficult days, as we are saying goodbye to players and men who have written Milan history. It must be a celebration for those lads who are leaving and I thank them for giving their all. Unfortunately you cannot hold back time," said Allegri.

"To be here for 10 years and win so many trophies means you have a very strong mentality. We're finishing a season and an era."
