Emre Can says training with Juventus is more difficult than with Liverpool.
The Germany international spent four seasons at Anfield before signing with Juve as a free agent last summer.
He told DAZN and Goal: "I already complained to Jurgen Klopp about the hard training in Liverpool! But the training here at Juventus is a bit tougher.
"We have to run even more, do more strength training. It was a big challenge for me at the beginning. But now my body has got used to it."
