The Light Blues are unable to buy new players until next January and have to wait until September 1 before they can register free agents.
With no option but to make the most of the squad he already has at his disposal, Perry believes the remainder of the season is the ideal opportunity to impress the manager.
The centre-half is fit again after a hernia operation and keen to make an impact.
Perry said: "The manager has to concentrate on the players he's got at the moment and we're just looking to do the best job we can.
"If that means playing as many games as possible, and really cementing your place in the team and the squad, that's great.
"I've got my operation out of the way now and, with games coming thick and fast, it's a little bit tiring.
"But, in terms of general fitness, it's the best I've felt."
