That's sort of his point.
Our defensive worries are weakened by having technically superior offensive players who don't lose the ball and give opponents a chance to make the 2/3 passes.
We play a high line. If you're not capable of keeping the ball in the final third, you're always going to be under threat due to the high risk/high reward nature of the high line.
It's the exact same for Liverpool and City. Except they're much better offensively than we are and either create more due to players being suited or just have much better offensive players than us on a technical level. Ultimately, most of the goals those top clubs concede are on counters or due to defensive errors.
Look at some of the goals we conceded. Kulusevski loses the ball easily due to passing to no one. Luton go up the other end and score. Son loses the ball due to not being able to hold the ball up, Newcastle knock it long, score (I think this actually happened twice) . Just to name two quick ones off the top of my head.
