West Ham midfielder Manuel Lanzini could be out of action for around a month after limping off during the 2-0 win over Liverpool, according to Hammers joint-chairman David Gold.
The Argentinian, just back in the side following a thigh injury, had impressed against the Reds at Upton Park, hitting the post before being forced off late in the first half.
Gold confirmed in a post on Twitter the player would undergo further tests to determine the extent of the problem, but said the 22-year-old could be out of action for up to six weeks.
We will know more about Manuel's injury after the scan on Monday but it could be 4/6 weeks. He was superb today. dg https://t.co/ktip4Y2PJi

In his post-match media conference, Hammers manager Slaven Bilic said he hopes the playmaker, signed on loan from Al-Jazira, will not be absent for an extended spell.
"They have told me a little bit and I will hear more tomorrow. It is not big. It is the same, it is not the hamstring or the muscle, it is some kind of abductor and the tendon. I hope it is going to be like they have said now, just a little bit [of time out]," he said.
"If you watch the games again, the impact he made against Southampton and the way he orchestrated today with 22 players on the pitch, but with him bossing the game, [you can see] what he means to us."
