Hamann believes that Hughes is just the man to take the Blues on from last season's ninth-place finish in the Premier League.
He will start his third season at Eastlands under a third Blues manager following Hughes' arrival from Blackburn ten days ago.
And though it is no secret that City's players were sorry to see Sven-Goran Eriksson go at the beginning of this month, the former Germany international is glad that owner Thaksin Shinawatra managed to attract a manager of Hughes' quality to the club.
"Sven did a good job last year, and I think it was a bit harsh to sack him," Hamann told the Manchester Evening News.
"The chairman made a decision, and he got a very good replacement in Mark Hughes - who did a great job at Blackburn."
