Chelsea star Antonio Rudiger will miss the rest of the season.
Rudiger was forced off during 1-1 draw with Manchester United on Sunday.
The Germany international is now due to have an operation in Italy.
Rudiger's left knee will be operated on by Professor Pierpaolo Mariani at the Villa Stuart clinic in Rome. The Chelsea doctor has also travelled with the centre half and he will be there until Thursday if all goes to plan.
The 26-year-old has made 44 appearances for the Blues this season.
