Tottenham are preparing a bid for Borussia Dortmund star Marco Reus as the Germany international continues to stall over a new deal. The winger's contract will expire at the end of next season and if he views his future elsewhere, Dortmund may want to cash in this summer. Spurs are ready to take advantage of the uncertainty and make an offer for the 28-year-old. Liverpool are also understood to be keen on Reus who has struggled with injury in recent years but appears to be reaching form again.
