Jurgen Klopp revealed that Philippe Coutinho and Dejan Lovren are facing spells on the sidelines after suffering injuries in Liverpool’s League Cup win over Stoke on Tuesday night.

The pair pulled up with hamstring strains in the first half of of the first leg of the team’s semi-final clash against Stoke, which the Merseysiders won 1-0.

Recalled Kolo Toure then became the third Liverpool player on the night to suffer an injury when he suffered cramp in the closing minutes of the clash.

Asked how long Coutinho and Lovren will be out, Klopp told Sky Sports afterwards: “We had two bad injuries, I don’t know how bad. You watch longer British football than myself so you know what it means, usually.

“It’s a big shadow over the game for us, the injuries. I don’t know how serious and we have to wait for this.”

Klopp confirmed afterwards that Mamadou Sakho, who withdrew before the match with injury, is also expected to miss Friday night’s FA Cup tie away to Exeter although he is optimistic that Toure was only suffering with cramp.

However, Coutinho and Lovren are almost certain to miss the landmark Premier League matches against Arsenal on 13 January and Manchester United on 17 January, as well as fixtures against Exeter in the FA Cup on 9 January, Norwich in the Premier League on 23 January and Stoke in the League Cup semi final return leg on 26 January.

They joins a lengthy Liverpool injury list that already includes the likes of Jordan Henderson, Daniel Sturridge, James Milne, Martin Skrtel and Divock Origi.
