The Red Devils entered negotiations with BVB late on in the transfer window regarding Shinji Kagawa, and now it has emerged that Red Devils chiefs sounded out the Bundesliga side for a swap deal.
Speculation suggests that United were ready to offer £16m plus the Japanese playmaker for Hummels, but the German giants dismissed their attempts.
Despite the majority of Louis van Gaal’s headline grabbing signings having been attacking stars, the Dutchman wanted the World Cup winner all summer, with his composed playing style seen as useful in the club’s new 3-4-1-2 set-up.
Dortmund were however against letting their star enforcer leave, yet they still managed to pull off a deal for Kagawa – who re-joined them after two disappointing years at Old Trafford.
United are likely to re-visit Hummels in January, but they may have to wait until next summer to have a genuine chance of landing him.
