Brescia striker Alfredo Donnarumma is adamant teammate Sandro Tonali is the real deal.

A target for Chelsea and Juventus, Tonali is with the senior Italy squad this week.

Donnarumma told Calciomercato.it, "The president (Alessandro Triboldi) has made significant investment this year, he has big plans.

"We must improve our young people.

"The fact that Tonali can stay in January? I hope so, he is essential for us. For him it will be good too, he will continue to develop in this jersey, before he has to leave."
