Liverpool manager Jurgen Klopp insists Daniel Sturridge's focus has not wavered despite his looming Football Association misconduct charge for breaching betting rules.

The 29-year-old has stressed he "categorically has never gambled on football" and has requested more time to contest the charge having initially been given until Tuesday this week to respond.

Klopp said the striker remains in contention for Saturday's trip to Watford.

"You don't see any influence on Daniel in training, so that's good," he said.

"I don't know, I cannot say actually, anything about the case. It is difficult to get information about it but in training he is completely normal: in good shape, looks sharp, looks focused, but of course it is something you do not want to be involved in.

"But from my point of view, and until someone tells me something different and as long as he trains well, he is 100 per cent in contention."

Liverpool skipper Jordan Henderson also is set to be available despite suffering a knock on international duty.

Klopp believes Sadio Mane's new contract is a statement about the progress Liverpool have made.

The Senegal forward signed a long-term extension on Thursday and his commitment to the Reds has delighted his manager.

Klopp told a press conference: "It's a big sign. To extend a contract is more than a signing, it is a statement.

"It shows a bit of change the club did in the last few years. A few years ago players felt they had to leave the club to make the next step."

Klopp added that reports summer signing Fabinho could leave the club as "crazy".

"He played three of the last four," Klopp said. "Now is the most intense period of the season and he's used the time to adjust to what we want. Of course he will not leave, it would be completely crazy."
