Manchester United and Liverpool will be on high alert after the real value of Borussia Dortmund midfielder Marco Reus' release clause was revealed.

According to the Express, the German midfielder is available for £20m and not the earlier reported fee of £30m. This news will be music to the ears of all pursuing clubs, as a player of top-quality is available at a price that none of the top clubs will mind spending.

The Red Devils have been keen admirers of the Dortmund star and have been linked with a move for the midfielder during the current transfer window. With Louis van Gaal planning a major overhaul of the squad, he could be tempted to test the Bundesliga club's resolve with a bid for the player.

The Merseyside club are also rumoured to be interested in the German international and manager Brendan Rodgers has sufficient funds, if he wants to bring Reus to Anfield. The former Swansea City boss has been the busiest manager in the transfer market and has already brought in seven new players, but is still interested in strengthening further.

Moreover, with the added information that Reus has refused a contract extension, the Premier League rivals might double their efforts to get their man.

Even Reus' agent Dirk Hebel has confirmed the interest of various clubs and feels that his client's presence will make any team around Europe a better side.

"Marco would improve any of Europe's top clubs so it is only natural that many of these clubs are making moves for him," Hebel said, as quoted on Sky Sports.

However, the 25-year-old midfielder, who is recovering from a serious injury sustained just before the start of the World Cup has come out and quashed all the speculation after he revealed that he was happy to remain in Dortmund and that his only aim is to get fully fit and start playing again.

"I do not want to repeat what I've said before. I am very happy to play for Dortmund. My main goal for now is to return to optimal fitness. There is nothing more important to me right now," Reus said as quoted by French newspaper Le10sport.
