Ruud van Nistelrooy reactions confirm the change Manchester United have to make

During the stoppage to check the goal-stopping bounce off Joshua Zirkzee, Danny Welbeck sidled over to the touchline and caught the eye of Ruud van Nistelrooy. The pair amiably embraced.

His tap-in on Saturday was the 100th of his career. Welbeck's first, a spectacular piledriver against Stoke City at the Stretford End, was in November 2008.
