“I’m not going to get carried away, I’m just going to remain calm,” Ferdinand told BT Sport after the final whistle.
“I’ve had my little moment of excitement in the studio. You’ve got to take these moments. Casemiro, that man there, Marcus Rashford another one – two huge components in everything that’s good about Manchester United at the moment, and the spirit showed today.
“I spoke about being fragile in recent years, this Man United team. Going 1-0 down against a team like Manchester City in the past, they would have absolutely folded.
“Today they gathered their concentration, remained calm, came back into the game, and they’ve come out of it with three points. That’s a massive, massive shift in mentality in this squad now and it only bodes well for the future.”
United defeated City 2-1 on Saturday to move to 38 points, just one behind their rivals. They face Crystal Palace on Wednesday.
