Manchester United are leading the race to sign Ilkay Gundogan after it emerged that Borussia Dortmund are ready to cash-in on the midfielder as a result of his reluctance to sign a new contract with the Bundesliga giants.
According to The Express, the 24-year-old - whose current deal expires in the summer of 2016 - is eyeing a move away from the Westfalenstadion, and Jurgen Klopp wants to avoid a repeat of the scenario that saw Robert Lewandowski depart on a Bosman free transfer.
The Red Devils have been credited with an interest in taking the Germany international to Old Trafford as Louis van Gaal seeks to strengthen his midfield department in the New Year.
However, they could face stiff competition to secure the player's signature with Chelsea, Arsenal and Liverpool also believed to be monitoring the situation closely.
Gunners boss Arsene Wenger is known to be on the lookout for a new defensive midfielder at the Emirates Stadium, while Brendan Rodgers has been linked with a number of different players in a bid to improve the Reds fortunes at Anfield this term.
Jose Mourinho's alleged interest in Gundogan is perhaps the most surprising, given the strength and depth of his current squad at Stamford Bridge, but either way it should help Dortmund drive up the fee they can demand for a player that has just under 18 months left on his existing contract.
Gundogan has made no secret of his ambition to one day test himself in the Premier League, and that dream could finally become a reality if one of his reported suitors makes an offer deemed acceptable by Dortmund in the January window.
The Daily Star reports that he could be available for £20 million, which would represent a relatively modest fee compared to some of the other asking prices being bandied about by other clubs for similar players in an inflated mid-season market.
