Macheda, who joined United’s youth academy from Lazio, made his debut in 2008 during the Sir Alex Ferguson era and left in 2014 after several loan spells away.
The Italian scored four goals across 19 Premier League games for United and played a total of 36 games before joining Ole Gunnar Solskjær’s Cardiff.
Speaking to Rio Ferdinand’s YouTube channel, Macheda was asked what it was like coaching Ferguson’s star-studded side during that period and was asked who was the most intimidating team-mate he faced.
Ferdinand’s co-host suggested the likes of Nemanja Vidic and Ryan Giggs, but Macheda revealed it was a certain Sky Sports pundit he found the most daunting.
“I’d say Gary Neville,” Macheda said as Ferdinand and his co-hosts looked somewhat bemused at the suggestion.
‘Sometimes he would kick you out of nowhere and you wouldn’t know why. The ball would be on the other side of the field and he would just kick you.’
‘A bully!’ Ferdinand said with a smile before Macheda laughed and added: ‘Yes, a bully! He bullied people.
‘But the rest, no. There were good grades in training. Against Nemanja Vidic and Rio Ferdinand… I found it motivating just to train against them.
‘It was great to try to improve, to try to beat them.’
Macheda was then asked to name his ultimate 5-man team from those he had played with during his career.
‘They will all be United players!’ he added. ‘OK, I would put Rio Ferdinand, he was technically top [defender] and also Nemanja Vidic, he just wanted to kill people.
‘Then I would put Paul Scholes together with Cristiano Ronaldo and Wayne Rooney. There we have five!’
