Milan trained on Wednesday morning as they prepare an attempt at mounting a miracle comeback in their UEFA Europa League tie with Arsenal.
Gennaro Gattuso's side were beaten 2-0 at the San Siro in last Thursday's first leg as first-half goals from Henrikh Mkhitaryan and Aaron Ramsey inflicted heavy damage.
Arsenal will be strong favourites to advance into the quarter-finals when the sides reconvene at the Emirates Stadium on Thursday night, but Milan haven't fully given up hope.
