A) I've been under the impression he wants to leave because he's third choice for one position, rather than having available game time (playing two strikers) and simply deciding he's fed up.
B) Which gives you my answer for the Bony/Aguero thing: if I thought we intended to play two strikers, I think Dzeko would be fine staying and Pellegrini would've played him & Iheanacho rather than rehearsing a system we don't intend to use.
C) Maybe I just missed it -- which sustained or somewhat credible link to a striker have we had this summer?
Txiki & Feran previously preferred one striker. Pep prefers one striker. Vieira plays one striker. We played with one striker to finish the season. I don't know, it just seems to add up from where I'm sitting. In the end, though, we could probably go round and round on this (and drive people insane in the process). You're welcome to have the last shout. If you believe we're playing two strikers, and you want Ibrahimovic to be our 4th striker (by order of signing, not hierarchy) so be it. Not going to be able to convince you otherwise.
