Yes, 'not very strong'. Relatively, of course. EPL teams tend to be overrated on this forum. Strong team wouldn't allow KdB to fly freely across the pitch, wouldn't let one of the world's most talented CMs (Pogba) fail so miserably. Mou is slightly outdated and is not the greatest rival for Pep anymore, IMO. I find Klopp and even Conte more dangerous for our league chances. That's what I want to say mentioning Barcelona or any other strong European side as a benchmark.
I think City has a very long way to go, as Pep's said himself recently. It will take months and years of progress to get to the top (and maybe the strengthening of EPL will help that). You may find me too critical, but the only reason of my doubts about the current team's state is that I expect Pep to build the world's best team in 3-5 years, no less. Not just 'CL winners' but the most dominant team.
As for EPL, yes, City is the best team here no doubt.
