Former Inter Milan midfielder Stephane Dalmat says they cannot to lose Nicolo Barella.
The champions have already sold Achraf Hakimi (PSG) and Romelu Lukaku (Chelsea).
"(Antonio) Conte's farewell was only partly a surprise for me, because even before winning the Scudetto, I had realised there was something not working between him and the club," Dalmat told FCInter1908.
“Lukaku was very important for the title win and allowed the team to reach a new level. He'll be difficult to replace, as will Hakimi, who had an extraordinary season.
"It's going to be tougher to challenge for the title, that's for sure."
