Marco Reus has thrown fuel on the fire with regards to rumours surrounding his future after having a very public spat with teammate Roman Weidenfeller, reports the Daily Mail.
The German international was at the business end of an angry rant from Weidenfeller during Tuesday's German Cup semi-final against Wolfsburg.
Weidenfeller was reportedly angry at Reus' refusal to track back, leaving the Dortmund defence outnumbered on the break. The goalkeeper later dismissed it as 'a tactical direction' but Jurgen Klopp later admitted that he was forced to intervene as the argument continued behind closed doors.
Dortmund have attempted to play down the incident but the news of a continuation of the on-field spat is very much public knowledge and is now being used to link Reus with an exit from the Westfalenhallen stadium in the summer.
The news would have likely rung loudly around Old Trafford with David Moyes believed to be keen to sign the winger in the summer.
Manchester United are reportedly willing to pay Borussia Dortmund as much as £30m and offer the player £200,000-a-week.
If plans go Moyes' way, Reus will be one of a number of world-class stars to arrive at Old Trafford this summer.
With as much as £200m to spend in the transfer market, Moyes wants to overhaul the Manchester United squad and stamp his authority after a poor first season in charge.
Reus' international teammate Toni Kroos has also been heavily linked with a switch to Old Trafford this summer.
