Liverpool and Manchester United could snap up coveted Borussia Dortmund midfielder Marco Reus for as little as €25m (£19.8m).

The Premier League rivals have been monitoring Reus all summer after it was thought he was looking for a move away from the Westfalenstadion.

That interest could turn into a concrete offer for the 25-year-old after it was revealed his contract with BVB could have a buy-out clause of just €25m.

It had been thought a bid of €35m would activate the player's release clause.

But in an interview with German tabloid Bild, Bayern Munich executive Karl Heinz-Rummenigge said Reus was not as expensive as had been previously thought and he believed the player's get-out clause was valued at €25m.

In another interview, Heinz-Rummenigge said: "I believe that it is difficult for Borussia Dortmund, [because of] the buy-out clause for Reus. The player has high demand among the European top clubs, regardless of Bayern."

Dortmund hit back with repsonse:

"Borussia Dortmund has noted with some irritation that Karl-Heinz Rummenigge is currently discussing internal BVB matters in a three-day rhythm in the media," read the statement."We are sure that it is quite clear to anybody interested in football what intentions lie behind such remarks. Karl-Heinz Rummenigge is also fully aware that his behaviour is only going to further damage an already tense relationship between Borussia Dortmund and Bayern Munich.

"Naturally as employers, we are going to continue to follow our principles in future and not discuss any details of our employees' contracts in public."

Reports last month said Bayern themselves were in the race to pluck yet another Dortmund talent to the Allianz Arena, after buying Mario Goetz and Robert Lewandowski.

Dortmund have tried to stymie interest in Reus, whose contract with the Bundesliga club still has three years remaining on it, by reportedly giving him a 30% pay rise to €6m a year, and manager Jurgen Klopp has previously laughed off claims he is willing to part with the German international to either Liverpool or United.

Klopp told a press conference last month: "Marco and Mats [Hummels] will be playing for us next season. I can assure everybody that there is no sign at all that either of them want to leave."

But Liverpool and United could be encouraged to test Dortmund's resolve with a bid of around £20m - less than the Anfield club paid for Adam Lallana, Dejan Lovren and Lazar Markovic and less than United paid for Ander Herrera and Luke Shaw.
