Spezia striker Andrey Galabinov insists Bulgaria can upset Italy tonight.

The two nations meet in their second World Cup qualifier.

While the Azzurri opened up their campaign by beating Northern Ireland 2-0, Bulgaria lost 3-1 at home to Switzerland.

“I missed the first game with a slight physical issue. It was nothing serious, I was just tired and wanted to be ready for this match, as facing the Azzurri is special for me," said Galabinov in his press conference.

Galabinov's Spezia earned a shock 2-0 Serie A victory against AC Milan this season.

He added: “I don't think (Gigio) Donnarumma is unbeatable, of course I will try to score. I hope personally that Italy under-estimate the game, even if we have to focus only on our own performance."
