Borussia Dortmund defender Mats Hummels has played down fresh transfer speculation.

Hummels is being linked with Manchester United, where his former Bayern Munich coach Louis van Gaal is expected to be installed as new manager.

The Germany international is also wanted by Barcelona after their FIFA transfer ban was suspended last week.

"I do not think about it," insisted Hummels.

"It is better to stay here to be a major figure of this championship than to have a secondary role elsewhere."
