The Argentinian, who has scored 26 goals this term, has missed five games with a hamstring injury but is set to return to training on Tuesday.
Nasri said: "It is going to be a big boost for the team, but you cannot disrespect Alvaro (Negredo) and Edin (Dzeko).
"They have done a great job too. It will be good when another striker comes, and with Stevan (Jovetic) and them we can rotate and be more fresh."
