Former Chelsea striker Tony Cascarino has questioned the form collapse of Liverpool ace Roberto Firmino.

The Reds forward struggled with his distribution as his side limped to a 1-1 draw with West Ham in London.

“Klopp will have been kept awake by Roberto Firmino's performance," Cascarino said. “I cannot remember seeing him play so badly in a Liverpool shirt.

“The Brazil forward's game is about intelligence, movement and decision-making, and technically he is very skilful, but it fell apart here.

“He was not at the races. Others had off days, too.

“Firmino's decline was dramatic; he could not pass the ball five yards.

“Is he ready for the final charge?

“What makes it worse is that Liverpool do not have the greatest depth in that position and they do not have a supersub that they can throw on to win the game."
