West Ham United star Manuel Lanzini is expected to be on the sidelines for a month with a hamstring injury, according to The Mirror.

What happened?

Manager David Moyes expressed concern for the playmaker following the Argentine's substitution against Bournemouth on Saturday.

The 24-year-old lasted 64 minutes before he was hauled off with a suspected hamstring strain.

The Mirror reports that the extent of the problem is now known, and Moyes will be without Lanzini for the next four weeks.

The former River Plate player is expected to miss the FA Cup fourth-round tie against Wigan Athletic, as well as Premier League matches against Crystal Palace, Brighton and Watford.

Lanzini will hope to be back in action for the trip to Anfield to face Liverpool on February 24.

Can West Ham cope?

The injury setback is bad timing considering that the team are on a strong run of form, and Lanzini has been a major part of that.

The playmaker has scored twice and produced four assists in his last nine outings in all competitions.

Lanzini and Marko Arnautovic have, in particular, linked up well in recent matches, but this injury blow means that the pair's fluidity will now be absent from upcoming fixtures.

On top of that, The Mirror claims that striker Andy Carroll will be sidelined for three months with a hairline fracture in his foot.

Being without Carroll is nothing new to West Ham, but Lanzini's absence could stop short the team's seven-game unbeaten run.
