Pep's experiment to rotate Man City players is working, they can catch Arsenal because they play abysmally without Saka and Martinelli. Their inconsistency is the reason they were unable to test Liverpool.
There is a 7-point difference between Manchester City and Arsenal. There are still 11 more weeks to go. So it isn't impossible work Guardiola to catch up.

But it depends on how far Arsenal will continue like this. They were horrible in their last 2 PL games. Not even being able to score a goal...
But this 7-1 win vs PSV was confusing. If they can score this many goals without Saka and a proper centre-forward then why were they like shit previously?

Arsenal's big win in the Champions League really makes me not sure Manchester City will be able to overtake Arsenal, but if I consider the fact that PSV may have a quality below the Premier League teams then, maybe the victory can be a natural result. Because afterall, in the Premier League Arsenal can also lose and only draw in one of the matches against teams that are in the lower zone of the standings. Thus, for the results in the Premier League I believe it will still be difficult to maintain its consistency moreover, Arsenal also still have to make rotations and efforts to prepare the team to play in the Champion League. Thus, I will still believe Manchester City will still have a chance to be able to threaten Arsenal in second place in the standings.
