Slightly different.

Less need to protect starters in this upcoming match, but uncertain who will play. Still, many bench players like to grasp the opportunity to show what they can do. Like Europe's other powerhouses Milan is extremely deep. In spite of fielding their second stringers against Udinese the game was very even:
