AC Milan coach Massimiliano Allegri insists they were "unlucky" after a shock opening day defeat at home to Sampdoria.

A second-half header from Andrea Costa clinched the three points for the promoted club.

"The first half was played with a little fear against a side that defended very well. After the break we started fairly well and then went behind to the only corner they had," said the Coach.

"We hit the woodwork, forced goalline clearances and saves. I cannot ask for anything more from my players at the moment.

"There's no point acting like victims now and we must instead restart from the good things seen. The performance showed there are quality players in this side, but there are always going to be difficulties at the start and we need calm to grow slowly."
