When he was playing for Porto in Portugal, legendary striker Cristiano Ronaldo was turning out for Sporting Lisbon.
The latter was establishing himself in the football world while McCarthy had already found his footing.
The two attackers were reunited in English football and in the 2006-07 season, the former Bafana Bafana forward scored 18 goals, one more than Ronaldo.
Just recently, McCarthy was employed as Manchester United strikers' coach.
He worked with Ronaldo before the attacker fell out with the then-manager Erik ten Hag and left for Al Nassr.
In his recent interview with iDiski Times, McCarthy explained why he did not remind Ronaldo of the times he beat him on the pitch.
