The midfielder thinks a failure to replace key figures within the squad has damaged the champions, who have lost both their opening Serie A games

Daniele De Rossi believes Juventus may struggle to cope this season as he does not think they have adequately replaced Carlos Tevez, Andrea Pirlo or Arturo Vidal.

Goals from midfielder Miralem Pjanic and summer signing Edin Dzeko handed Roma a vital 2-1 win over the champions on Sunday, despite Paulo Dybala’s late consolation.

The defeat underlines a disastrous start to the season for last term’s double-winners, with Udinese having won 1-0 in Turin on the opening day, and De Rossi feels the loss of some key figures in the dressing room is taking its toll.

“Juve created a cycle based on certain players,” he said after the match. “Some can replace them, some can’t. You have to spend a lot to replace players like Vidal or Tevez. And nobody can replace someone like Pirlo.

“We had an incredible first half. We fell asleep a bit for the final 10 minutes but we controlled the game. But it must also be said that a great team that wins the Scudetto can’t even afford to fall asleep for 10 minutes.

“It’s wonderful that we had the courage to play our football with heads held high. Don’t forget Juve were in the Champions League final a few months ago.”
