Igor Stimac has said even Pep Guardiola or Jose Mourinho could not do better than him in the current circumstances with the Blue Tigers.
Manchester City will face Chelsea in the finals of the Champions League later on Saturday in Porto. Guardiola's side has already won the Premier League and Carabao Cup this season.
Guardiola said at the start of the week he is still not sure of his team lineup for the final, but the selection debates are likely at left back and in defensive midfield.
Chelsea, though, have beaten City twice in the last six weeks, first in the FA Cup semi-final and then at the Etihad Stadium in the league.
Guardiola's award came just days after it was announced that City defender Ruben Dias had been voted the footballer of the year by England's Football Writers Association.
Aguero played his final game for Manchester City at the Etihad Stadium on Sunday and he ended up scoring two goals after coming in as a substitute.
Guardiola has also confirmed that Aguero is fit for Manchester City's last Premier League clash against Everton on Sunday.

Pep Guardiola said that winning the Premier League is always the team's primary objective at the start of a season.
Sterling hasn't been influential this season, with Guardiola admitting that Foden and Mahrez have jumped ahead of the striker in the pecking order.
The Spaniard, who has guided Barcelona, Bayern Munich, and Manchester City to multiple league titles, had also expressed his desire to know more about cricket.
Since Guardiola joined in 2016, City was eliminated by Monaco in the last 16 before losing in the quarterfinals in three straight seasons.

Manchester City defeated Borussia Dortmund 2-1 in the first leg of the Champions League quarterfinal on Wednesday.
Guardiola said the club is open to the possibility of changing that approach but does not believe it would be a game-changer for City, which has never won the Champions League.
Manchester City manager Pep Guardiola stated that it is impossible for players to be ready every day to compete.
The 58-year-old will return after holding off competition from Victor Font and Toni Freixa, the other two candidates to gain enough support to make the final stage.
