Mario Gotze has dropped a major hint that he could join Liverpool in the summer.

The Germany World Cup winner admits he could leave Bayern Munich at the end of the season and has spoken of his excellent relationship with Anfield manager Jurgen Klopp.

The 23-year-old forward’s contract expires in 2017 and he has yet to open talks over a new one.

Speaking in his native Germany, Gotze revealed that his future was up in the air. “It is still uncertain what to do next after this season,” he explained.

Asked specifically about a possible reunion with Klopp at Liverpool, he said: “We worked good together.”

Liverpool have been linked with a £37million bid to prise Gotze from Bayern in the summer transfer window.

The versatile forward, who scored the winning goal in Germany’s 2014 World Cup final win over Argentina, was brought through the ranks at Borussia Dortmund by Klopp.

However, Gotze has struggled to establish himself as a regular in the Bayern team under Pep Guardiola since joining Germany’s biggest club in the summer of 2013.

He is currently injured and expected to be out of action until February, which means any approach won’t happen until the summer.

Gotze had a terrific record at Dortmund under Klopp, scoring 31 goals and supplying 44 assists from 116 appearances.
