Runaway Premier League leaders Liverpool have given manager Jurgen Klopp a new contract.

The German has signed an improved deal through to 2024, the Reds announced this morning.

Klopp, who moved to Anfield in 2015, guided Liverpool to the Champions League title in June and currently has them eight points clear at the top of the Premier League. 

Back to the day-to-day and the German is down to just two fit centre-backs for the foreseeable future after Dejan Lovren was ruled out with a hamstring problem.

The Croatia international, who had suffered what was believed to be cramp in last weekend's win at Bournemouth, was forced off in Tuesday's victory over Red Ball Salzburg and left the stadium limping.

On Lovren's availability ahead of the visit of Watford, Klopp said: "Out. He has a muscle injury, worse than last time. No time-frame. He's out."

With Joel Matip still probably at least two weeks away from a return from a knee injury it leaves just Virgil Van Dijk and Joe Gomez as his two fit central defenders.

"It's a concern. At the moment we have two and we need to take care of them and wrap them in cotton wool and ask how they want to train," Klopp added.

"We have the kids too - Ki-Jana (Hoever) and Sepp (Van Den Berg). We have 'defensively minded' midfielders where we can use different systems. I have a lot of ideas but I hope to not have to use them." 

On his new deal, the former Borussia Dortmund and Mainz boss said:

"For me personally this is a statement of intent, one which is built on my knowledge of what we as a partnership have achieved so far and what is still there for us to achieve," he said.

"When the call (to manage Liverpool) came in autumn 2015, I felt we were perfect for each other. If anything, now I feel I underestimated that.

"It is only with a total belief that the collaboration remains totally complementary on both sides that I am able to make this commitment to 2024."

The club said the manager's assistants Peter Krawietz and Pep Lijnders had also agreed new deals.
