Delio Rossi has warned former club Lazio to not sit back and defend against Milan in Friday's Serie A opener.
The capital club begin the season with a daunting trip to the Stadio Giuseppe Meazza as they take on the League champions.
"Lazio have to go there and play an open game," the out of work tactician insisted. "That's the only way they can get anything out of the match.
"It certainly won't be easy for Edy Reja's side, but you would be making a mistake if you try to put up a barricade.
"You have to go there and play your own brand of football, to play without any fear. Only by doing that can you take the points home."
