See, I disagree with that statement. Watch yesterday game and see how our gameplan relies on passing the ball to attackers surrounded by 3 opposition players, because we don't do any build-up play, no dragging defenders, no cohesion. You buy Messi, put him in our team and he struggles - coaching has to be addressed first.
The bolded part is not really true:
The general rule is if the xG-xGA difference is below 0,7-0,8, the most likely result is a draw. Basing on that we can conclude we've overachieved in 3 of the last 5 games. Which is what happens when you rely on individuals winning you games, and that's OK but it can't be the only strategy. In general looking at this graph it seems we're doing much better against decent sides than poor sides, and unsurprisingly our biggest issue is creating chances against them. Our best run of form was with Fred and McTominay in midfield too, but Bruno form is a big factor as well.
