According to The Mirror, Dortmund are now interested in Can and are set to battle it out for his signature.
The report claims that Can is stalling on a new contract with Liverpool, which has alerted some of the big clubs in Europe.
Foreign clubs are able to sign Can up on a pre-contract in January, allowing the midfielder to join on a free transfer next summer.
Can’s contract expires at the end of the season and the report claims that he is hesitant over signing an extension.
He is open to a return to Germany – with Dortmund interested – though Juventus is also an attractive proposition.
The Mirror also claim that Can would only sign a new deal with Liverpool if a release clause was inserted.
