The 46-year-old has rejected reports suggesting he will leave the club and insists he is "super happy" at Signal Iduna Park.
The German coach has been repeatedly linked with the role at Old Trafford since the departure of David Moyes on Monday, but Klopp dismissed the speculation, adding that he has had no contact from the United hierarchy.
"It's a bit uncomfortable to give someone a rejection if no request has come,” said Klopp, talking during a news conference. “But it must indeed be made apparent anyway.”
Klopp, who coached Mainz before taking over at Dortmund in 2008, signed a new contract in October that commits him to the club until 2018, and the 46-year-old was clear-cut about his future despite labeling Manchester United as a “really great club.”
“There are about 1,000 reasons why I am super happy to work with this club,” Klopp said.
Dortmund takes on Bayer Leverkusen at the BayArena on Saturday, with BVB currently sitting in second place in the Bundesliga, 17 points behind champion Bayern Munich.
