Liverpool have received a massive injury boost ahead of their clash against Watford, with Jurgen Klopp revealing that Mamdou Sakho may be in contention to travel to Vicarage Road, having recuperated from an injury he picked up in November. The Reds are going through an injury crisis at the back, with four players unavailable for their game against West Bromwich Albion last weekend.

Dejan Lovren will miss the rest of the festive period with a laceration on his knee, while Joe Gomez and Jon Flanagan could be out for the rest of the season with serious knee injuries. Sakho's return will be a major boost for Klopp, who is without a win in his last three games in all competitions.

Sakho will slot alongside Martin Skrtel at the back, who has been ever-present in the Liverpool backline. The Frenchman was the first choice player under Klopp before the setback and injuries.

"Mamadou has trained completely normally. It is a good situation. He started normal training last week and now he has completed this week. If it stays like this he will be ready," Klopp told Liverpool's official website.

"Now he's had many weeks out, everything is different, but when we all work together as a team it is easier for the centre-halves to play a normal game. We want Mamadou's quality and his strength but the team has to help him too."

The game against Watford is a must-win for Klopp, with the Reds currently ninth in the league with 24 points, one behind their hosts. A loss here will open up a five-point gap between themselves and top four rivals Manchester United and Tottenham, with the latter's win over Southampton on Saturday taking them above United on the table and on to fourth spot.
