Empoli coach Maurizio Sarri is happy for Mirko Valdifiori over his first Italy call.

Valdifiori has earned his debut Italy call-up for games against Bulgaria and England.

Sarri said: "We are very happy for him, but we have nine players in seven different national teams, so there are concerns over fatigue. Obviously, the happiness is greater than the concern.

"I think Valdifiori could be worth several million now. I think Empoli can set the example, so this economic crisis can actually help Italian football create something different."
