Manchester United target Mats Hummels 'reflecting' on his future at Borussia Dortmund
Borussia Dortmund defender Mats Hummels has left his options open amid speculation he may leave the club in the summer.
The German centre-back gave an interview in Kicker magazine last week in which he demanded a stronger Dortmund team for next season, otherwise he may consider his own future.
The Westphalians seem certain to miss out on a place in the Champions League next season while they may not even qualify for the Europa League, and Hummels has admitted again he may not be sticking with the club for much longer.
"That doesn't mean that I am leaving, it just means I'm reflecting," he told Sky television following a 1-0 defeat to Bayern Munich at the weekend.
"There's no particular tendency one way or the other. It's just thoughts going through my mind. It will all become clearer in the coming weeks."
In 2007, when he moved to Dortmund from Bayern, he turned down an approach from Hoffenheim and said that was a "gut feeling".
"It's going to be the same again this time," added the 26-year-old, who still has two years left to run on his contract with the Westphalians, but has already attracted attention from several other clubs around Europe.
Manchester United were reportedly willing to offer up to 40 million euros for his services - an amount Dortmund may struggle to reject if they cannot count on earning that sort of money from the Champions League next season.
