English Premier League suitors and the likes of Barcelona and Bayern Munich have been put on alert after reports of one of the most exciting playmakers in the game at the moment rejecting a new contract at his current club emerged.
Marco Reus is a coveted player, with the Germany international setting Europe alight with his performances for Borussia Dortmund and the national team over the last couple of years.
The likes of Barcelona, Bayern Munich, Manchester United, Arsenal and Liverpool have all been linked with the 25-year-old at some point in time, and all of those interested parties have been handed an opening now, with Reus, who cruelly missed the World Cup due to injury, rejecting a new contract offer from Dortmund, according to the Bild.
Reus still has three years left on his current deal, but the report suggests the player has turned down the offer to extend his stay at the Westfalenstadion, and could be open to a move away.
The playmaker's current contract also has a release clause of £27 million, which will come into play from next summer, according to the report.
Buying Reus for £27 million would be an absolute steal for any club, even if they have to wait another season. And if Reus' stance of not signing a new contract remains, then Dortmund might have to consider selling their premier player this summer to ensure he doesn't walk away for the knock down price.
Manchester United have kept tabs on the midfielder for a while and Louis Van Gaal is thought to be a big admirer. While most of the links with a Dortmund player have been towards Mats Hummels, with reports at one time even suggesting a move was as good as done, Reus has also been in the reckoning.
Van Gaal and his 3-5-2 formation have worked out quite well so far during this preseason, and with the Dutchman having scores of forwards in his lineup already, it does beg the question just how he might be able to fit in a player of Reus' mould.
However, when you have a player of his quality, there is always room, especially if the likes of Shinji Kagawa, Wilfried Zaha, Nani and Ashley Young are expected to bid goodbye to Old Trafford before the transfer window shuts.
Reus was apparently looking forward to a move to Barcelona this summer, but after the Catalans turned their attentions towards Luis Suarez, the chance of that transfer has died down a little.
Bayern Munich is always an option for a big Germany star, and with Toni Kroos, albeit a different player to Reus, moving to Real Madrid, there might be room for Pep Guardiola to work with yet another brilliant playmaker.
Dortmund will definitely do everything in their power to stop that from happening again, though, having already seen Mario Gotze, the World Cup goal hero and all, and Robert Lewandowski take that particular journey.
That does leave the Premier League clubs with an opportunity to make a move (assuming the report is true, of course), and United will do well to fend off interest from Liverpool and Arsenal, who has Reus' idol in Tomas Rosicky in their ranks, to complete what would be a truly marquee signing.
But, as Jurgen Klopp has already suggested numerous times, Reus is a Dortmund player and any interested club will have to make a mean offer for the Germans to even consider selling, even if that release clause does get activated next summer.
