Luis Diaz has left Liverpool's mid-season training camp in Dubai after suffering a setback in his recovery from a knee injury.
Diaz hasn't featured for the Reds since sustaining a knee problem during the first half of the 3-2 Premier League defeat at Arsenal on October 9.
The winger didn't require surgery and subsequently underwent rehabilitation both in his home country of Colombia and at the AXA Training Centre before travelling with Liverpool for their training camp in Dubai earlier this week where he was expected to make his comeback in the forthcoming friendlies against Lyon and AC Milan.
