Cleverley is on loan at Aston Villa from Manchester United, and the Germans have joined a list of teams interested in signing him that includes Everton, Arsenal, and Villa themselves.
The midfielder is waiting until the end of the season to decide where he’ll play next season.
Sky sources understand one big factor is his international future. He is desperate to get back into the England squad after starting all the qualifiers leading up to the World Cup.
Cleverley has hinted that he could stay with Villa, insisting money is not a factor.
“I don’t think any Premier League players are going to be short of a quid or two,” Cleverley said. “You have just got to be happy first of all.
“And I am at this club, so let’s see where we go from there. I think first and foremost you have to be playing at a club where you fit in.
“Where you’re playing in the position where you want to play and where you like the manager, the lads, this club ticks those boxes.
“We’ll just see what happens but first the club have got to offer me something. Those talks haven’t taken place yet. I just know my contract runs out on June 30 at Man United, that’s my position.”
