Klopp was tipped to take up the job at Old Trafford before the appointment of the Dutchman, who took over following the sacking of David Moyes at the back end of last season.
At 47-years-old Klopp is likely to be a highly sought after coach when he eventually leaves BVB with his current deal set to expire in 2018.
We’ve taken a look at three key questions and some initial reaction based on the report.
What if van Gaal succeeds?
There’s every chance that van Gaal could achieve real success at United. It’s far too early to judge him based on a few competitive fixtures and at 63-years-old he could realistically be the club’s manager for the next decade and could win major pieces of silverware during that time.
What would it mean for United’s interest in Mats Hummels and Marco Reus?
It would certainly help but again it’s impossible to predict when or if Klopp would end up at United. Either German could have already pushed for a move away from BVB with United one of the major sides interested and they clearly respect and admire him as a coach.
Why wouldn’t he extend his contract?
He could well do. BVB have been very protective over their manager whenever there has been any speculation over his future and this is no different. The German side are well placed, and under no pressure, to make him a decent long term offer next year or the year after.
Here’s some reaction from Manchester United fans.
