Jurgen Klopp has hinted that Jordan Henderson could face an extended spell on the sidelines.

The Liverpool captain did not feature in Saturday’s 2-0 defeat at West Ham after suffering discomfort in his heel during the win over Sunderland last Wednesday.

Henderson has been troubled by a persistent heel injury this season and Klopp has all but ruled the midfielder out of the first leg of Liverpool’s League Cup semi-final against Stoke.

“We have to wait,” said the German of Henderson at his pre-match press conference on Monday. “What’s happened with the tendon is painful. There is blood around the heel. We can’t rush it.”

Meanwhile, Klopp has confirmed that Daniel Sturridge is not ready to play any part against Stoke on Tuesday night.

“Daniel had some problems, not serious, but he couldn’t make the next [training] session,” said the Liverpool manager. “When he’s had a row of sessions, I will pick him.

“I won’t hold him back. But in this moment, because he hasn’t had one session with the team, he’s not available.

“Daniel had his last pre-season in 2011. During that period we load bodies with strength. We’re trying to fill his body with energy.”

Liverpool travel to the Britannia Stadium for the first leg of their League Cup semi-final on Tuesday night, with the second leg at Anfield scheduled for 26 January.
