The reporter claims that the £25m-rated Strootman is a "clear favourite" of Louis van Gaal, the Netherlands boss who was confirmed as the new United manager on a three-year deal earlier today.
A deal cannot be completed this summer because of Strootman's ACL tear, but van der Kraan believes he will join the Old Trafford club from PSV Eindhoven in January.
With Strootman currently injured, United have been linked with Feyenoord midfielder Jordy Clasie. But the Dutch journalist thinks this is nonsense, and Van Gaal will wait for Strootman to recover from injury.
"No, not all all," when asked if Clasie could be Van Gaal's first United signing. "He only plays him [for the Netherlands] at the moment because he doesn't have Kevin Strootman.
"If I was a Manchester United fan I would look forward to the moment Strootman comes to Old Trafford. He's a clear favourite of Van Gaal.
"He won't come now. They can't even do an advanced transfer because the guy suffered cruciate knee ligament damage about a month ago. Even if they wanted to sign him now he wouldn't get through a medical. I can see him signing in January though."
United are expected to back van Gaal in the transfer market this summer, with up to £200m available to the new manager. He will link up with United after he completes his World Cup duties with the Netherlands in Brazil.
