If, and it's a huge IF, we win both at United and Spurs, we'll be big favourites for the title, for we'll be likely to get around 90 pts again. I still think Arsenal won't get more than 88 pts (even if they win their next two games, I doubt it though).
Admittedly, if Arsenal win 6 pts vs Spurs and United and we win fewer than 3 pts, it will be a lot more difficult for us, for Arsenal will be 9+ pts clear after the first 19 games. They'll be favourites then. Also, if United win the games with us and Arsenal, they may be title challengers too. But we have the players and the manager to get on a winning run at some point and we are likely to do it.
Arguably, we are less likely to suffer from fatigue and injuries than Liverpool, for Pep has rotated key players much more than Klopp, plus only KDB (and Walker) from the key players are over 29 y.o., whereas Liverpool have 4-5 such players and it shows this season. Some problems this season may be traced back to the efforts from last season. Liverpool and West Ham have fallen off a cliff for a reason. Hopefully, Pep's ability to rotate will get us over similar problems. Those willing Pep to find his best XI and play it week in week out are being silly. Rotation is absolutely essential to our capacity to fight for all trophies every season.
