Borussia Dortmund defender Mats Hummels has insisted that he is happy at the club amid speculation over his future.

The Germany international has been heavily linked with a move away from Dortmund in recent months, with Manchester United thought to be keen on signing him.

However, the 26-year-old has claimed that he has no plans to leave the Bundesliga outfit soon.

"I am not really known as a globetrotter," he is quoted as saying by Sky Sports News. "I have been with two clubs in 26 years. Loyalty is important to me.

"The only thing I am concerned with right now is to play better than in the first half of the season. I was not satisfied at all with myself as one can imagine.

"I have gotten offers from different clubs ever since I have been with Dortmund. That's not a secret. I have always decided not to leave."

Hummels joined Dortmund from rivals Bayern Munich in 2009.
