Joel Matip will join Liverpool from Schalke in the summer, the German club have confirmed.

The centre-back has signed a pre-contract with the Merseysiders after rejecting a series of contract offers from the Bundesliga club.

Football Insider reported on Monday morning that Matip has agreed the terms of a four-year contract worth £60,000-a-week. The deal is worth £12.5million plus bonuses.

Speaking at a media conference on Monday afternoon, Schalke manager Horst Heldt confirmed the departure of the long-serving defender, who is out of contract in the summer.

“Since May last year we have had many intensive discussions, both with Joel and his advisor,” explained Heldt. “It was soon clear that factors we could not influence would be decisive in Joel’s decision.”

Matip, who has 27 caps for his country, explained why he has chosen to leave for Anfield .

He said: “I have always said that I would only leave Schalke for one reason: to get to know something new. I never even considered a move within the Bundesliga.

“Although my decision is definitely not easy, I am convinced that now is the right time to take this step.

“Schalke 04 will remain a big family for me. I was always proud to play for this great club. I will do everything in the next few months to get the most out of this season so I do not feel guilty.”

As revealed by Football Insider in January, the Merseysiders made a contract offer in January to the Cameroon international, who will not cost a transfer fee.

Manager Jurgen Klopp sanctioned a move for Matip, who has come through the ranks at Schalke and is well known to the German from his time in the Bundesliga.
