The reality is that even if that didnt happen he prob still wouldnt have called. Messi and Aguero will prob start and then you have Dybala prob on the bench and 2 subs in Martinez IF he isnt gonna start no point in taking him with potentially him causing issues or just giving other younger guys the chance to be on the bench. I am sure Icardi would like to be there regardless but when ur sub at ur own club goes and ur not u have to look at urself.
Forwards: Lionel Messi (FC Barcelona), Sergio Aguero (Manchester City), Paulo Dybala (Juventus), Angel Correa (Atletico Madrid), Lautaro Martinez (Inter), Matias Suarez (River Plate)
