No.
Our performances: Wins have been completely deserved, we haven't been lucky in winning and I think some of our defeats have been unlucky. What we have seen and what has been debated this season has been stylistically, we've lost our mojo, our dominance, our shots on goal have dropped and our shots conceded has increased. Largely what has been debated has been our FB's and our Midfield as the root cause. But this has also been with the backdrop to almost our entire first team unable to participate in pre-season, which has probably been the reason why we've had so many injuries and mental fatigue experienced throughout the entire season.
To emphasise this further, if we failed to sign a single player again this season and we didn't sell a single player do you think this team will perform better or worse next season? I'd say it will perform better, solely because they would have a break (although our brake will actually be 3 weeks less than most in the league due to our participation in the CL final) and a pre-season. I would, however, expect us to still to experience issues, especially against top opposition because our midfield lacks the quality to control and dominate at that level (although Sissoko's new level is genuinely like a new signing in that position, you and I both know that there are better more technical options that we can aspire to), the same too in our FB positions, but even there we have a glimmer of hope with Rose improving and KWP who IMO is better than Frodo.
What we have matured into is a team that is fucking hard to beat.
City is way, way, way ahead of anyone. Liverpool jumped +20 pts this season, their level of performance was a not representative of this points differential, yes there underlying numbers were better than ours and they were very worthy of 2nd place, they have been incredibly fortunate in at least five games this season (that's approx 15pts!!).
TDLR: We are a very, very good team. We can improve by focussing on a small handful of positions (FB and Midfield), these improvements will largely be getting control of our midfield and having more rounded FB's who contribute as modern day FB's are expected to do (and have done for us). The result should be more shots on oppo goal and fewer oppo shots on our own goal. It's not rocket science. But we will be better next season just because our preparation will better (normal) and we will be playing our home games at home.
