Manchester United boss Ole Gunnar Solskjaer has ruled out competing for departing Manchester City striker Sergio Aguero.
The Argentine striker, 32, will leave the Etihad this summer after a decade — and 257 goals.
Former United greats Paul Ince and Dimitar Berbatov have both urged Old Trafford boss Solskjaer to swoop for Aguero.
But the Norwegian insisted no player should move between the rivals.
He said: “I wouldn't expect any player who has played for a club for ten years to want to go to their local rivals. It's not for me.
“When I played for Manchester United, if a rival club tried to sign me and I had gone — well, where's the loyalty?
“Loyalty is one of the values I really, really put highly.
“I know we are professionals but when you play for United you don't go to City. We have had examples of that and I didn't really agree with it.
“I won't name names but you all know who I mean — enough said."
Carlos Tevez enraged Reds fans when he controversially switched to the Etihad in 2009.
Treble-winning keeper Peter Schmeichel's move to City seven years earlier also left everyone at United fuming.
