Liverpool boss Jurgen Klopp has revealed he snubbed a chance to manage Manchester United while he was still in charge at his former club, Borussia Dortmund. He admitted the Red Devils offer was made in April, a month before Sir Alex Ferguson retired from his Old Trafford post.

United appointed David Moyes and after a dismal performance under the former Everton boss, the club decided to show him the exit door and replace him with Louis van Gaal. The Dutchman will take his men to Anfield as his side face the Merseyside club in a Premier League clash on January 17.

Klopp took the reins at Liverpool after Brendan Rodgers was sacked in October. The German would have been the manager of the visitors on Sunday, had he agreed to take the United job.

The ex-Bundesliga manager hailed the Old Trafford legend as the "John Lennon of football" and disclosed that he had had conversations with Ferguson. His commitment to Dortmund convinced him to continue at Signal Iduna Park before stepping down after the end of the 2014/15 season.

"We spoke. We spoke not a lot but, for me, it was a lot. It was a big honour, the whole talk, to be honest," Klopp explained, as quoted by Goal.com.

"There was a time [when United were interested] but I could not leave Dortmund. That is it. You are in April and you are in the middle of the planning for next season.

"You have this player and this player and this player who is coming in but then you are not there any more? That doesn't work. Not in my life anyway.

"I did not hear about a real offer but, if there was, I could not have done it. I first had to finish the job with Dortmund and then think about other things. Maybe that is not the smart way but that is my way. Of course I was loyal to Dortmund. It was the same at Mainz."
