Bologna coach Daniele Arrigoni says there's more to come from his team after their opening day shock at AC Milan.

"We did some good things but we are also lucky," the 48-year-old tactician maintained. "In my opinion Milan didn't deserve to lose.

"We didn't turn in the super performance I hoped for and the team need to improve.

"A lot of factors are involved when you win a game like that. Certain things can turn a game and if they had gone 2-1 up it could've ended very differently."

Former Juventus hitman Marco Di Vaio opened the scoring and Francesco Valiani hit the winner with a blast from outside the box.

"Valiani scored a great goal but he didn't have a great game and Di Vaio could and should do more," a critical Arrigoni rasped.

"I will be curious to see how my side play against Atalanta."
