Hammers boss injured himself during 5-1 defeat at Liverpool in the Carabao Cup

West Ham boss Julen Lopetegui is on crutches after injuring himself on the touchline during their painful Carabao Cup defeat at Liverpool.

The Spaniard hurt his calf as he jumped in frustration towards the end of an excruciating 5-1 drubbing at Anfield.

Lopetegui was hobbling gingerly around West Ham's Rush Green training ground on Thursday and looks likely to still be using crutches when they travel to Brentford this Saturday.

Nevertheless, Lopetegui had to admit: "I can't play in this match, for sure.

As for the injured players, Germany striker Niclas Fullkrug has suffered a setback in his recovery from the Achilles and calf problem which has kept him out for the last three matches.

"Fullkrug is not available until now," he added.

"The truth is I don't know. We thought he would be available this week but unfortunately he was not so we have to wait, but at the moment he is out.

"He has one problem in his Achilles calf. A little injury, not important, but until now he is out."

The Anfield annihilation came hot on the heels of last weekend's meek 3-0 home defeat by Chelsea, as questions are beginning to be raised about West Ham's direction under the new manager.

Next they travel the length of the District Line on Saturday to a ground where they have never picked up a point.

"We know we have to improve," said Lopetegui, who will also be without Edson Alvarez in west London following the midfielder's red card on Wednesday night.

"We are just starting. The demand is high. The Premier League is going to be long for all of us and these players are going to improve. I am sure of this.

"It's true we need one win and we want to win the next match. The next challenge is Brentford. A very good team, a very complete team. Very strong away and especially at home.
