West Ham have made a “massive mistake” by not signing a striker during the January transfer window, according to Gabriel Agbonlahor.

The former Aston Villa and England striker, speaking exclusively to Football Insider, claimed there is no way the Irons can rely on winger Andriy Yarmolenko to lead the line if Michail Antonio picks up an injury.

The Hammers sold record signing Sebastien Haller to Ajax last month leaving Antonio as David Moyes’ only senior recognised striker.

Yarmolenko started up front in their 4-0 win over League One side Doncaster Rovers in the FA Cup and also filled in against Liverpool last weekend when Antonio was substituted.

Assistant manager Alan Irvine told the press after their victory over Doncaster that he was encouraged by the Ukrainian’s performance as a striker.

Asked whether he was thought Yarmolenko could lead the line for West Ham, Agbonlahor told Football Insider correspondent Connor Whitley: “No way.

“I saw Yarmolenko when he came on at the weekend. He had no physical attributes. He gets bullied very easily.

“I think West Ham have made a massive mistake by not bringing in another striker.

“Antonio looked tired at the weekend and he does get injured.

“They’ve got no back up striker which is incredible for a Premier League club to only have one striker.

“I think West Ham fans are going to be very frustrated because the position they are in now, if they had bolstered their squad with a striker they could probably look at the top six.

“Just for Antonio as well, some competition. It’s not just about when he gets injured it’s about competition.

“Very strange from West Ham to not get a deal done. I thought Josh King would’ve been perfect for them and I’m sure West Ham fans will be very frustrated.”
