City brought the former Leicester City star to the Etihad in the summer of 2018 for a then club record fee of £60million and the 28-year-old struggled to make a real impact in his first campaign at the club.
"The price tag doesn't give you any advantages at City. This wouldn't be the case at any other club. Riyad felt unconfident and I reminded him to keep calm," Kompany told the Guardian.
"We need to look at the bigger picture – the fact he can have an impact even in the last minute of the season because of his exceptional talent. You share a similar journey with people who spend a lot of time on the bench.
"People forget I was on the bench. But I got the goal against Leicester and then, in the last match of the season, Riyad got us back in the game with an assist and a goal against Brighton. He did it when it mattered the most."
