Liverpool alerted as £20m target tipped for Dortmund return

Liverpool have been alerted after Borussia Dortmund chief executive Hans-Jaochim Watzke revealed that he is open to letting Mario Gotze return to the club, Bild reports.

The 23-year-old left Dortmund for rivals Bayern Munich back in 2013, but has struggled to hold down a regular role ever since his arrival.

It is believed that he shares a strained relationship with current boss Pep Guardiola, but his situation could change given that the former Barcelona manager is set to take over at Manchester City next season.

Reds boss Jurgen Klopp is keen to be reunited with the forward given that the pair previously worked together during their time at Dortmund.

When asked about a possible move for the Germany international, Watzke admitted that there are no ongoing negotiations for Gotze, but added that he is open to seeing him make his return.

“Mario is Bayern’s player. His contract runs until 2017 and I have not heard, neither from the club or him, that they wish to end their collaboration,” he said.

“Under the current conditions, this is not a topic for us. But for every player who has merits for this club the door remains open, no question about it.”

He has only started six Bundesliga matches this season, featuring another three times as a substitute, so far managing to score one goal while providing another three assists.
