Morata facing four weeks out

The 22-year-old will also be sidelined for at least the first two games of the Serie A season – Juve’s opening fixture with Udinese and their trip to Roma – after being told to rest for 30 days.

In a statement on their website, the Italian champions said: “Alvaro Morata will be sidelined for up to 30 days after suffering a torn soleus muscle in his left calf during yesterday evening’s training session.

“Having departed the workout early, the striker underwent tests today in Shanghai to reveal the full extent of the damage.”

Morata joins Sami Khedira and Giorgio Chiellini in the treatment room while Andrea Barzagli is also rated doubtful to face Lazio for the first trophy of the Italian season this weekend.
