It may be the optimist in me, but I don't think we're that far off from putting up a proper title challenge and even winning the league.
Like many have stated earlier, City are in some trouble - I don't really rate their defenders except Laporte and Walker. Laporte has struggled with injuries and Walker is getting older. Fernandinho is on decline thanks to his age and they lack a player who can do his job when he isn't there. Rodri hasn't set the league alight and Gundogan has been avergae. On the top end of the pitch, Aguero is 32 and has started signs of slowing down and Jesus hasn't exactly progressed from where he was 2-3 years ago. Unless they spend a fortune to address all these areas, they wouldn't be getting 90 odd points.
Coming to Liverpool, they've been lucky with injuries this season and it would be interesting to see if they can even continue to put in the performances they have put this season week in week out next year. They've played as well as title winners for 2 seasons in a row, and like we saw with City, it's tough to sustain such a run for the third year. Nearly all the players in their team are of similar age bucket and you would expect them to start declining in the next couple of years. Lastly, their underlying statistical data (xG and xGA numbers) point out that they've been incredibly lucky in a lot of their games this season. Unless they add more depth to their attack and defence (as they arguably have less depth than even us), I can see their competitors leave them behind especially with 5 subs a game rule.
For the sake of it, I'd address Chelsea as well. They've definitely performed better than what most people expected this season and players like Mount, Tammy and Pulisic have exceeded expectations. They've bought Werner and Ziyech which seem like good pieces of business. However, it seems that strengthening their defence (which has been their pain point all season) on back burner. I don't think any of the back 5 is a player who belongs to a title winning side (maybe Rudiger at a stretch). They've already conceded 46 goals this season, and considering they aren't even being linked with any CB, one can safely assume that their defence will remain as bad as it has been.
We, on the other hand, have been improving ever since Bruno joined us. We have a young side and have had moments of bad luck this season, more often than other big sides - conceding some worldies and all. I also think that thanks to our players being really young, we've lacked maturity in the 1st half of the season. Defensively, we're giving away lesser chances now, we're creating more and more every game, our midfield is playing vertical passes cutting across lines, our attackers seem much more confident our pressing has been really good, and I can go on. If we add Sancho and a DM and maybe a CB, I really think that we'd be having a hell of a starting XI. We'd also be having players like Greenwood, Ighalo as backups, James as a sub against tired legs would be an interesting watch as well. Add to that, McT, Fred as backup CM options is as good as any other team. Should our players not suffer from long term injuries, I genuinely think next year would present us with a really good chance of winning the league
