Liverpool's UEFA Champions League semi-final opponents Villarreal have a number of injury concerns ahead of Tuesday's second-leg tie.
The Reds head to Spain with a 2-0 lead and are seen as favourites to progress to the final where they will meet the winners of Real Madrid vs Man City.
Villarreal knocked out Bayern Munich in the quarter-finals and will be up for the fixture as they look to mount a major comeback. But they may have to do so without a number of key players. Monday morning's training session saw six players miss out, some due to long-term issues and others were unexplainable by their absence.

Talented winger Arnaut Danjuma missed Monday's training session and is a major doubt to feature against Jurgen Klopp's side, having missed Saturday's defeat to Alaves. “Danjuma has also had some discomfort. He has not trained today with the group and tomorrow morning we will see if he is in a position to play as well."
The Yellow Submarines were without Gerard Moreno for the first-leg at Anfield and Raul Albiol and Francis Coquelin both picked up knocks last week. All three trained prior to the return fixture and are expected to give Emery a fitness boost by starting on Tuesday night, although Moreno has missed a number of fixtures recently due to a reoccurring hamstring injury.
Villarreal will also be without teenager Yeremy Pino. Pino was another absentee from training, with Emery confirming: "Y eremy, it is true that he has an injury that will make him miss out.”
Former Reds defender Alberto Moreno will not come up against his old teammates as he recovers from a knee injury.
