West Ham United defender James Tomkins has conceded that injuries to Enner Valencia and Dimitri Payet are a "massive loss" for the club.
The Hammers will be without Payet for three months after he sustained an ankle injury in their draw against Everton, while Valencia has also been ruled out for an extended period.
However, Tomkins has backed other players in the squad such as Manuel Lanzini to replace the duo's impact on the pitch.
"It's unfortunate Enner and Dimi have got injured because they're two important players for us - they're game changers," he told Sky Sports News.
"Manu has done brilliantly for us already this year, and he looks a real spark on the pitch. He can change the game in a minute - you saw what he did against Everton, and that's what he does every day in training.
"There's people like him, Mauro [Zarate], and Andy [Carroll] who offers a completely different threat. I still think there are goals in abundance, but it's a massive loss."
West Ham face Tottenham Hotspur on Sunday at White Hart Lane.
