The Argentina international has had a scintillating start to his time in England, but suffered an adductor strain in the 4-0 win over Blackburn in the Etihad Stadium outfit’s last game.
With a crucial fixture against Villarreal in the Champions League coming up on Tuesday, the Italian coach may rest his in-form frontman.
“Sergio could be ready for Saturday but I don’t know if we will take the risk. I am sure [he will be] 100% for Villarreal on Tuesday,” he told the side’s official website.
City’s form domestically has been good, but with only one point from two games in Europe, the English team need a victory against their La Liga opponents in midweek to keep their chances of progression alive.
Ironically enough, if Mancini does decide to rest Aguero for the Villa clash, the side are short of options in attack, with Carlos Tevez not currently being considered.
Mario Balotelli may be able to deputise however, as he seems to have shaken off a back knock that prevented him from inclusion in Italy’s Euro 2012 qualifiers with Serbia and Northern Ireland.
