Looking at our (rather excellent) start to our season, the one issue which I still have with the squad is the lack of depth* we have, now of course is does not matter at this stage of the season, but when we end up having to deal with the latter stages of the League Cup, the FA Cup, the Knockout Rounds of the Champions League and the last stages of the Title Race (times when City will need to play 2-3 games per week, not an easy task for teams in the EPL) then maintaining this level of performance is going to be difficult if not impossible. I mean even now there have been games when this problem has been exposed (The League Cup Game vs Wolves*, the EPL Game vs Arsenal** and the EPL Game vs Everton).
So with this in mind I feel that we are going to need to get another Left Back (Rose), 2 Centre Backs (Alderweireld and Vertonghen), another DM (Kante), another AM (Alli), 2 Wingers (Sanchez and O.Dembélé) and another striker (Kane)*** over the next 2 transfer windows assuming the squad limits remain the same to somewhat address this issue. However in my view if we are going to be challenging for the Quadruple every season those squad limits need to be relaxed and thus we are going to need more players than the ones I am suggesting.
*I know it is the League cup, but the fact is that a club like ours should not be struggling to beat a team like Wolves. No ifs or buts. Thank god Bravo saved our arses (A term I thought I would never use) that night.
**Considering the state of the Arsenal at the moment, we should have had a better result than just 3-1 against them. Which we would of got if we had more depth.
***If Agüero does leave City at the end of next season.
