The Gunners star is expected to leave the Emirates Stadium this month with United and Chelsea reportedly in the running for his
signature .
United are the favourites to sign Sanchez following reports Manchester City have dropped their interest in Sanchez due to the player’s financial demands.
And after watching his side beat Stoke City 3-0 in the Premier League, Mourinho refused to be drawn too much on the subject of the 29-year-old but admitted
there is "a chance" he could end up at Old Trafford.
“I’m not confident; just relaxed,” Mourinho told talkSPORT.
“[I’m] just relaxed with the feeling he is an Arsenal player and with the feeling he can stay there. Also with the feeling he can move, and if he moves, I think we have a
chance.
“But most probably, a player like him has other big clubs interested [in him], who knows?
“I think him; Mr [Arsene] Wenger and Mr [Ivan] Gazidis are the ones that know really well what is going to happen.”
Mourinho went on to reveal that Henrikh Mkhitaryan, who was left out of the United squad against the Potters, could be used as
a makeweight in a potential agreement for Sanchez.
The Portuguese said: "I didn't select him today because I wanted players fully focused.
"I understand that with so much talk and so much speculation, it is not easy for Mkhitaryan to play, to play at home, with this feeling that \(it) can happen, maybe it doesn't happen.
"So I prefer to protect him and protect the situation, and in the end of the transfer market, if he stays here, he is a very good
player. Let's see what is going to happen."
