Borussia Dortmund centre-back Mats Hummels is bored of answering questions about Manchester United.
"I don't want to talk about that topic constantly," said Hummels. "I did it a few weeks ago—and that must be enough."
Hummels previously slammed suggestions he had given former United boss Sir Alex Ferguson his word that he will one day join United, per Hannah Duncan of the Metro.
"To clarify it: this supposed 'promise' is simply fictitious," he noted on Twitter.
Pete O'Rourke of Sky Sports provided comment from Dortmund:
Borussia Dortmund general manager Michael Zorc insists the club is yet to receive any bids for the services Mats Hummels.
