Lanzini could be out for six weeks
The Argentinian has just from a thigh injury and hit the post today before being forced off late in the first half.
Gold confirmed on twitter that 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.
Gold told his followers: “We will know more about Manuel’s injury after the scan on Monday but it could be 4/6 weeks. He was superb today.”
In his post-match press conference, the Hammers manager Slaven Bilic was a little more optimistic and said he hopes the playmaker will not be absent for a further 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”
