Icardi is a striker but he is not playing a lot this season and he scored only 3goals in the league this season.
Mouse kean have been enjoying his time at City of lights he is in a good form and getting some goals in so if PSG wants to bring Aguero he will most definitely be the one to make Moyes kean and Mbappe to work harder as he got a lots of experience.
Icardi and Moise Kean are the two players who are actual strikers but Icardi has been out due to injury and haven't played in a while but Kean is a young player and has been brought on loan from Everton, he so far is playing well and have heard some rumours to make his move permanent when loan deal expires. Not sure if he has impressed Pochettino but he sure did impressed his previous manager Tuchel.
Aguero could be a good move for PSG as well. Feels like either would be Aguero or Moise Kean.
