The German defender is believed to be somewhere near the top of new manager Louis van Gaal's transfer hitlist this summer, however it seems as though his raid for the Dortmund man isn't quite going to plan.
Manchester United transfer news
With Nemanja Vidic and Rio Ferdinand out of the picture, the Dutchman was said to be eyeing a bid in the region of €20 million for Hummels - something that Dortmund boss Klopp has rejected out of hand.
He told the 19:09 Uhr show: “What are we talking about today? Mats to Manchester United? For how much? €20m (£15.8m)? With those kind of sums can you forget that straight away.”
He also ruled out that another Manchester United target, Marco Reus, would be on the move in this transfer window.
However despite Klopp's insistence that Hummels won't be sold, TalkSPORT report that the deal isn't dead just yet. Executive vice-chairman Ed Woodward has left the club's tour of north America having previously told Manchester United fans to 'watch this space' as he works with Van Gaal to secure new signings.
Now TalkSPORT's Dom McGuinness has claimed that Manchester United are still in with a chance of signing the 25-year-old who was key to Germany's World Cup success despite what has been said.
“Ed Woodward has left the tour on, what he claims is, general business but we do read into that transfer activity,” he told Hawksbee and Jacobs. “He’s already back trying to work on that.
“As with all the big clubs they’ve been linked with everybody. Mats Hummels is the key one. [Borussia Dortmund manager] Jurgen Klopp has already said that’s not happening, or they can forget it if they’re offering €22million.
“I wouldn’t write that off yet.”
If Manchester United could seal a deal for Hummels it would provide a major boost for the club's fans. The arrival of both Ander Herrera and Luke Shaw marked the first signings of the Van Gaal era but things have gone a bit quiet since then.
They were heavily linked with moves for Arturo Vidal and Angel di Maria, however those deals appeared to have stalled. If they are unable to land Hummels, or indeed Reus, then Manchester United will have missed out on the vast majority of their top targets for a second straight summer.
