Mario Gotze has revealed he has been in regular contact by text message with Liverpool manager Jurgen Klopp.

The Germany World Cup winner has opened up the possibility of a reunion with his former Borussia Dortmund manager in the summer transfer window.

Gotze made his comeback from a five-month injury absence in Bayern Munich’s 5-0 win over Werder Bremen on Saturday.

Speaking afterwards, the 23-year-old discussed his relationship with Klopp, admitting they are in regular contact.

“We are texting now and again,” Gotze told German TV station ZDF TV. “He was my coach at Borussia Dortmund, but there is nothing special.”

When asked whether they he had spoken with Klopp about a possible transfer to Liverpool, the forward replied: “No.”

Gotze has admitted in the past he could leave Bayern Munich at the end of the season and has spoken of his excellent relationship with Klopp.

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

He added: “It was nice to return. I am just pleased that I was able to play again.”

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

Pressed on his plans beyond this season, Gotze said: “It hinges on many factors. Everything else will show in the future.”

“We are still in the current season but, sure, it’ll be important what the new coach [Carlo Ancelotti] thinks.”

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 played 54 minutes on Saturday in what was his first league action since tearing an abductor muscle in October.

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

In other Liverpool news, Klopp has already begun to look towards a summer revamp with his scouts in Italy to check out a potential £12million player.
