Manchester United splashed out £19m in a deal confirmed on Monday to sign arguably the hottest striking property in European football.
It is a clear statement of intent from Old Trafford as boss Sir Alex Ferguson aims to go out with a bang in his final season in charge next time around.
Van Nistelrooy, 24, crashed onto the Dutch League scene with PSV Eindhoven in 1999, when his 31 goals earned an international call-up and the Dutch Player of the Year title.
But life turned sour last season. United were set to sign him last spring but the deal broke down after he sustained a serious knee injury. Out for almost a year, Van Nistelrooy has successfully returned and is now gearing up for the Premiership next season.
Goalkeeping coach Hans, a former PSV player himself, commented: "I’ve seen him play quite a few times in Holland. He is a great player and has been a great finisher wherever he’s been.
"Ruud is a big lad and scores a lot of goals not just with his feet but with his head. I don’t think it will take him too long to settle down.
"He will definitely score goals here and I’m looking forward to seeing him play. My only concern is how the knee holds up. I personally still think it is quite a risk to pay £19m for someone who had a serious knee injury. The surgeons can look at it but you never know.
"The people in England are going to see another very good player but I’m afraid it’s not at Tottenham but at Manchester United."
Hans agreed that it was a case of all-conquering United setting the standards again.
"Over the last couple of years Liverpool and Arsenal have tried to catch up with United but United are always looking to go that extra step," he pointed out.
"They have now signed one of the most expensive players in the world. That’s the standards other clubs have to try and match."
But he insisted that is exactly what new boss Glenn Hoddle and the club’s new board were all about.
"We’ve seen when the new people came in that they set their standards out straight away," he added. "They want to get as quickly as possible back into the top six, that’s where Spurs belong and that’s what we have to work on."
