The Argentina international scored his 100th Premier League goal on Tuesday night in the 1-1 draw with relegation-threatened Newcastle United.
Despite standing in an offside position when heading past Karl Darlow on 15 minutes, Aguero marked his 147th appearance with his domestic ton.
Since his £38 million move from La Liga heavyweights Atletico Madrid in 2011, Aguero has become an undisputed world superstar.
The 27-year-old has scored consistently each season under Roberto Mancini and Manuel Pellegrini, helping City claim the 2011-12 and 2013-14 league titles alongside two League Cup triumphs.
Despite Kompany’s fluency in five different languages - including German and French - the Belgian international found it tough to correctly highlight Aguero’s value to the team.
As quoted by the Sun, the defender, who returned to first-team action at St. James’ Park following a month out, said: “Sergio Aguero has been a major player for us and there are not enough words to describe how important he is.
“We just hope he can carry on his career like this, it’s hard to come across a player who can have such an impact on games like he does.”
