Diafra Sakho is set to make his return for West Ham against Watford

West Ham forward Diafra Sakho is in line to make his return from injury against Watford on Wednesday, manager Slaven Bilic has confirmed.

The 26-year-old has missed the Hammers' last three matches after picking up what the club described as a "minor knee injury" in training.

A social media post from Sakho, prior to the 3-3 draw with Arsenal on April 9, had sparked rumours of a falling out with Bilic, something which the Hammers boss quickly denied following the match with the Gunners.

Sakho, who has scored only four times in the Premier League this season, has been deemed fit enough to return to the squad and could feature against the Hornets at the Boleyn Ground.

"We have a full squad. All the players are available, including Diafra Sakho who is back from injury. This is good, of course," Bilic said.

Sakho also missed three months of the season because of a thigh injury

Sixth-placed West Ham are currently seven points off Arsenal, who occupy the fourth, and final, Champions League qualification spot.

The 2-2 draw against league leaders Leicester on Sunday was West Ham's fourth successive stalemate and Bilic has warned his side they must start winning again to stand a chance of clinching a top four spot.

"The gap to top four is big but it can be reduced but we have to win games. We are still in a big race for a European spot," he added.

"Anybody who saw how we played at Leicester saw we have great team spirit and great motivation.

"We have a big game of football tomorrow night against Watford, so we need to talk about that and not a game that happened days ago.

Slaven Bilic has urged West Ham to rediscover their winning form

"We're playing good. Of course I'm not happy about conceding goals in recent games but this season is still fully on for us.

"There is no formula for turning draws into wins, but if you take Sunday, we were waiting for the game to finish instead of keeping the ball. It's not easy because the opposition take more risks but we should have played the game out with confidence."
