Who is out there that they can actually sign over the summer better than what they have now?
With the links to Sanchez and Mahrez and the use of Stirling as a forward I have a feeling that a player suited to operating in a wide position would be what they are after
Bale - not sure he fits Peps "philosophy" but he woul certainly add a different type of threat
Salah - not sure liverpool would sell but City would probably be one of the few teams with the cash to make them consider it
Hazard - with no CL then perhaps he could be an option
Muller - coming back to a bit of form and lets not forget he played 148 games for pep scoring 79 goals which is pretty good considering he isnt a traditional center forward at all
Griezman - they have not been linked much but with a relatively low buyout clause and them having very rich backers that could be an option
I think any of them would instantly improve the squad and to a varying degree all could be available
Then you have players like Brandt, Bailey, Kluivert, Lincoln, Malcolm who would probably be happy with more of a squad role and would add depth and huge potential to the squad
Given that Aguero seems to on average miss around 20% of the season simply buying better attacking players that lets you juggle your attacking options around that more efficiently (eg if stirling needs to play up top having better wide back up) will improve them... and there seems to be plenty of players that would fit that category - and of course the bids for sanchez and mahrez seem to suggest its an area they want to improve o as well.
