Manuel Lanzini is set for a spell on the sidelines after reaggravating a thigh injury against Liverpool last week.
West Ham’s owner David Gold confirmed on Twitter that Lanzini will miss five to six weeks of action.

The 22-year-old missed three weeks in December with a thigh problem, and he returned as a second-half substitute against Southampton on Dec. 28. In his first start back against Liverpool on January 2, he re-injured his thigh and was forced off after just 39 minutes.
Lanzini has impressed on his season-long loan from Abu Dhabi’s Al Jazira Club, scoring four goals in 12 Premier League starts.
The Hammers currently sit sixth on the table, but they have been riddled with injures throughout the season. Manager Slaven Bilic has been forced to go stretches without key players in Lanzini, Dimitri Payet, Diafra Sakho and Enner Valencia.
Bilic will look at the upcoming fixture list as a good opportunity to stay high on the table, with matches against five of the bottom-six teams during Lanzini’s absence.
