Honestly I can't agree or disagree with what you said but I understand where you're coming from,
For me personally, I've seen us win and perform strongly, I've seen us play terribly and win, or drop points, I've seen us play terribly and lose badly too.
I mean we smashed RBL, we smashed Southampton, beat PSG in Paris, and we did a number on City recently, and plenty of teams we've beaten in the league with good performances (not strong though) hence we sit comfortably in 2nd.
and then we lost to SHU, Palace, smashed by Spurs, lost to PSG at home and then beaten by RBL and crash out of UCL group stages.
This is a team that's extremely inconsistent and you don't know what you'll get on any given day.
