Former Manchester City goalkeeper David James has urged the club to 'move forward' by selling Sergio Aguero.
The Argentine has struggled with injury this season and will be out of contract next summer.
PSG manager Mauricio Pochettino wants to bring his compatriot to France, and James thinks City should oblige.
He told Stadium Astro: "I would let him go. This isn't taking anything away from him, he is a legend at Manchester City and always will be.
"There comes a point though when you are relying on him and can't move forward. They have proved that they can move forward without him.
"I think he has finished top goalscorer in the Premier League once, we are not talking about an Alan Shearer that did it three years in a row.
"As much as he is a Manchester City legend and a dangerous threat, he spends a lot of time injured, he isn't always the top scorer in the Premier League, and I think Manchester City are slowly trying to find that instinct where multiple high goalscorers are more important than one outstanding goalscorer.
"If you can get some money for him from PSG, especially considering the amount of time he has been injured, take it.
"It will be a fond farewell and I'm sure there will be a number of suitors that would like to come to Manchester City to fill his position."
