Aguero's wild lunge on David Luiz in City's 3-1 defeat to Chelsea last weekend has cost him the chance to help his side through the busy Christmas period.
Pep Guardiola has charged Aguero with improving many different aspects of his game this season, and the Argentine has responded.
As well as scoring 10 Premier League goals in just 12 games, the striker is doing more work for the team than ever before - and he has always been a vital player for City.
It makes sense, then, that he will be missed in the coming weeks.
Interestingly, the stats show otherwise. Despite scoring freely since signing for City in 2011, the club's results without him do not seem to differ too much at all whether he is in the team or not.
In fact, City have a win percentage of 63.6% with him in the side, and 64.3% without!
