"Sanchez is an Arsenal player", he added.
Arsenal forward Alexis Sanchez has not travelled with his team-mates for the trip to AFC Bournemouth this lunchtime as the likelihood of a January move to Manchester United has increased as reported by the Telegraph.
Normally, this is a fantastic deal for any admirer of the ex-Barcelona man, but the fact that he could join for free is even more appealing.
Earlier this week, Ferdinand appeared to suggest that Sanchez should pick the blue half of Manchester.
A host of top English clubs including league leaders Manchester City and their domestic rivals Manchester United have been linked with a move for the Chile worldwide, though the Blues boss has now confirmed that the Londoners will not be part of this.
"Sanchez is Arsenal player, I don't know but probably this weekend he is going to defend Arsenal colours so I don't think it's correct to say things about Alexis Sanchez", said Mourinho in press conference on Friday.
Just when you thought the race for Alexis Sanchez's signature was a straight head-to-head between Manchester City and United, along come Liverpool and their £142 million of Philippe Coutinho money to throw a major spanner in the works.
Fred: A frigid Sunday morning
EXTENDED: Early on Monday morning, we will see a chance of snow for most of our viewing area with a cold front pushing through. Accumulations will be minor, but it's possible that we could see and inch or two during the day on Monday .
When asked if United were interested in signing the 29- year-old Chilean global, who is out of contract at the end of the season, Wenger said "nothing is really concrete at the moment". "So he wants to fight as well for the Premier League, that's normal when you are at that level".
Manchester City are unwilling to pay more than £20m for the player whose deal at Arsenal expires in the summer, while title rivals Manchester United also want to sign the Chile worldwide.
'I think it's been a nightmare for Arsenal, a nightmare for the manger.' Souness said on Sky Sports ahead of Sunday's match.
And Yorke is not surprised to hear of United's interest in a player he believes is one of the best in the world. "So I wait, and I take a chunk of that contract as a signing fee", Wenger said.
"If somebody speaks about one of my players, to say we are interested or not I wouldn't be very happy".
The Arsenal boss said: "I had many conversations about him and we talked about the fact that people are always observing you with a microscope when you're on a short-term contract, but I've never questioned his professional attitude when he's on the football pitch". It is a hard period the first year.
