I can't remember much happening at all for the entire team during our preseason games. I'm not sure that's a good time to judge him. Especially when Mancini was popping molly before filling out the lineup card.
take preseason games out of the picture and what i said still holds up. most of the time icardi still looks like a really limited striker. he had a few good games where there was improvement, but thats not enough to say its not an issue anymore.
