The German centre-back played a key role in his nation’s successful World Cup campaign and is widely considered to be one of the planet’s very best defenders after a fine period with BVB.
United and Arsenal have been linked with moves for him since the summer, yet Hummels himself has insisted publically that he’s fully committed to Dortmund.
However, with his side sitting inside the Bundesliga’s relegation zone after a shocking start to the season, reports have suggested that he’s looking for a way out.
The enforcer is thought to be concerned at his team’s slide, and with the futures of star forward Marco Reus and manager Jurgen Klopp unclear, his stance has swayed in recent times.
Dortmund want to keep their man, but offers in the region of £47m are set to be accepted, although that figure may fall if he looks to force a switch.
BVB have lost a host of top players over the course of the past few years, including Mario Gotze and Robert Lewandowski – who both now play for bitter rivals Bayern Munich.
