Arsenal legend Ian Wright does not expect Radamel Falcao to be a Manchester United player next season.
The Colombian appeared to wave goodbye to fans at Old Trafford after being substituted off against the Gunners.
He said: "Falcao today, he was somebody who had an opportunity a couple of years ago when he went to Monaco, I think he should have came here.
"He was hot then, scored four goals against Chelsea. Everybody was courting him. He made the wrong move at that time.
"Today watching him, there's no way he should be at Manchester United."
Falcao was prolific for Atletico Madrid, scoring 70 goals in 91 games for the Spanish side, but was tempted by Monaco despite them not having Champions League football on offer at the time.
He suffered a serious knee injury in his debut season, and has not looked like the same player since returning to action.
Really it would have been better for him to stay at Monaco and rebuild, to have a bounce back year, and his United switch has backfired.
It's possible he realised his mistake in signing with the Ligue 1 side and was impatient to re-establish himself after the frustration of missing the World Cup, but United are unlikely to want to sign a striker permanently who has scored only four goals this season.
