Alvaro Morata has shocked Milan fans during the warm-up for the game against Lecce, showing off a new and extreme haircut.
It kicks off at San Siro at 19.45 UK time (18.45 GMT).

There had been doubts as to whether the Spain international would be in the starting XI, as he sustained a knock in training, but was passed fit.
During the warm-up at the Stadio Meazza, Morata was barely recognisable when he took off his hat to show a shaved head.
The former Juventus, Chelsea and Atletico Madrid striker has generally had a full head of hair, so this was a radical change from his usual style.
