Can't compare Aguero to Suarez. The latter would never accept the role and wages that's being offered.
Aguero isn't an idiot. He won't demand to play 80% of the minutes after being a bench player for City. If he comes he'll have to deserve his minutes. It's obvious he's not coming as the main #9.
I'm sure he'll be more useful than Braithwaite as he's an experienced striker who knows how to score.
Like I said before, we have the upper hand in these negotiations. Aguero isn't in a Haaland type position where he can demand astronomical wages from 5 different clubs.
Our finances are well known and our long term intentions with the #9 position as well, if Aguero wants to play for Barcelona before retiring he knows what kind of contract he can expect to be offered.
