Liverpool boss Jurgen Klopp has admitted he does not know when Daniel Sturridge will return to first-team action. The 48-year-old German confirmed the Reds striker is back in training, but that there is no timescale in place for his return to competitive football.

Sturridge, 26, has been plagued by injury problems throughout the season and Klopp revealed he will not be included in the Liverpool line-up for the third round FA Cup replay against Exeter City at Anfield on 20 January.

Asked about his striker's prospects of being fit to face Exeter, Klopp said, according to the Liverpool Echo: "No chance for Daniel. He has had a break in training because of some issues. He's now back training but losing time. But no team training since the Newcastle game. I don't know how long it is. That's not a situation we can think about him."

Klopp also addressed the future of Liverpool youngster Jerome Sinclair, who recently revealed he wants to explore the possibility of a move to Spain. The 19-year-old striker has been offered a new deal by the Anfield club, but plans to leave Liverpool when his contract expires in the summer.

"It's not important to get the highest wages of your life in your first year, it's about getting a good education. I like Jerome, he's a good talent. If he wants to stay with us then he's welcome, if not then we can't stop it," the Liverpool boss explained during a pre-match press conference.

"We need young players who want to learn, if they feel it's the right place to learn then good. We can do that next season but not now. There's no rush. I cannot make decisions for them, we can only offer things and first of all education."

Klopp also questioned Sinclair's suitability to the Premier League, which is generally considered to be more physical than other major competitions around Europe. "Jerome is very young, so in a situation he has skills but physically it's not easy for him in a central position in a Premier League game, to survive," the Liverpool manager said.
