Luis Diaz is expected to be out for up to three months after undergoing surgery on his knee, it has been reported.
The Colombian forward went off in October against Arsenal but had returned to training for the club's mid-season camp in Dubai this month.
However, after experiencing further complications on the tour to Dubai, it was announced he would be out for longer. He has now had surgery on his lateral collateral ligament and is unlikely to appear again before March, it was reported by The Athletic.
