Former Juventus midfielder Alessio Tacchinardi says they can compete with anyone in Europe - when Paul Pogba is fit.
The Frenchman is currently sidelined due to injury.
"I think Allegri can only be praised for what he's done this season," Tacchinardi told Tuttomercatoweb.
"They're one step away from the Scudetto, they've reached the Coppa Italia final and are in the top four teams in Europe.
"He's done a great job, and has also had the luck which you need to get to the end in a competition like the Champions League.
"For the future, I think a Juventus at 100 per cent, with the return of Paul Pogba can easily compete on a par with Real Madrid."
