People are just projecting. They like 4-3-3 because the top 2 teams in our league are using it successfully and they think that's the system that we play or at least
should play. But we're really lacking the hard working wingers and fullbacks that system requires to make it work in this league or CL.
Look how much ground the likes of Sterling, Salah, Mane, B.Silva cover. And also the ground Robertson, Walker, TAA, Zinchenko cover behind them to provide the width. And also the ball playing CBs they both have, that can play as high as CMs. How high-energy, high-pressing their midfield is? Training the system aside, which might even be beyond Ole's capability, how many players are we gonna have to change to make that system work for us? Can we even do it in one season, or at all?
I really don't know how people feel 4-3-3 is somehow our settled system. Mourinho was building up the side to play 4-2-3-1 or 3-5-2. Now 4-3-3 feels like the system least suited to our players tbh. And I don't think that can change unless we get 7-8 players (instead of 4) and spend well upwards of half a billion given the current market rates for players. Which I don't think there's any change it will happen.
