The Rossoneri head coach has been linked with a summer move to Roma, though the San Siro side have since denied these reports.

"At this time the games are easy to prepare for," the 45-year-old told reporters. "We have a motivation that goes beyond the opponent.
"Tomorrow's game will be difficult, though. Pescara went to Rome recently and did well. We have to pay attention to their qualities. But we are a team that needs to win.
"It is important that we get three points tomorrow because it would allow us to go into upcoming games with a greater peace of mind.
"I am at peace because I do not want to speak any more about my future. It has become an issue and that just doesn't make sense. We are all focused on third place. It is not respectful to talk about my future at this time of the season. We'll talk about it over the summer - first with the board ... and then maybe with the journalists."
The Milan faithful gave Allegri a show of support in their 4-2 win over Catania at the end of April and the club remain on track to secure a Champions League berth for next season.
