Celtic boss Gordon Strachan was also in attendance, adding to rumours that United's top scorer is currently red-hot property.
But Dennis Wise insists Beckford, again on target against Crewe, is going nowhere and said: "There's a lot of people looking at him but the problem for them is that he loves this football club. I keep being asked about Derby but, sorry Derby, we are a bigger club.
"If you were talking about the big four or five clubs, then maybe it's different, but I'm not going to let him go to a place like Derby. In fact, I'm not prepared to let him go anywhere."
