The Uruguayan joined the Red Devils on transfer deadline day on a one-year deal with the option of a further year after his contract at Paris Saint-Germain expired in the summer.
The 33-year-old scored an incredible 200 goals in 301 matches in all competitions for the French giants over seven years.
Rio Ferdinand believes Edinson Cavani is the man to help Manchester United’s young strikers
Cavani has bagged 35 Champions League goals in 62 games across eight seasons
Mason Greenwood has the opportunity to learn from one of the best strikers in the modern era
Ferdinand feels Cavani’s European pedigree and predatory instincts will rub off on 19-year-old England international Greenwood, who has scored 18 goals in 57 games for the club he joined as a six-year-old.
‘I said last transfer window that he’s one of the players I would have highlighted to buy,’ the United legend said on his YouTube channel.
‘We’ve got three supremely talented young strikers who are going to need assistance.
‘Martial is a prime example. He’s going to be suspended [after being red-carded after striking Erik Lamela]. You need someone to step in.
‘I think Cavani would suit in a lot of capacities. Mason would probably be the one to benefit most, to sit and watch someone like him on a daily basis, how he prepares, how he recovers, how he trains, the intensity levels he trains with through the week.
Anthony Martial is suspended for three matches after his red card for swiping at Erik Lamela
Ferdinand hopes Cavani will have a similar impact on the Man Utd squad to Henrik Larsson
‘He does score goals. Is he long-term? No he’s not. I played in a team where we brought Henrik Larsson in.
‘If you asked the strikers that were at the club, “did he bring value to our squad? Did he bring elements of his game that they could take?” Yes, 100 per cent.
‘If that’s the type of effect that Cavani can have with this group of players, then it’s worthwhile.
‘He’s a top player, experienced, gets goals. He’s someone I think is going to be good value to the club.’
Cavani last scored for PSG in their 4-3 win over Bordeaux in February this year.
With Martial suspended, he could be drafted straight into Ole Gunnar Solskjaer’s squad for the match against Newcastle United after the international break.
