3-man defence is used more and more these days, specially in Serie A. And after this season, this team has played 4 seasons with 3-man defence.
I'd say we stick to that if there are coaches available for that. And Juric might be since he was in fights (literally ) with his club already this summer.
Switching to 4-3-3 doesn't need an overhaul. We mostly need wingers and backups for CB and MF in the summer. If necessary, we can even switch to 4-3-1-2 right about now. Skirniar and Bastoni as CBs, Dumfries (Bellanouva-Darmian) as RBs, Gosens (Dimarco-Darmian) as LBs, Midfield the same as it is, with Mkhi, Correa or Hakan behind the 2 strikers. But if we switch back to the lone striker next season, Lautaro can take that spot with Thuram and Satriano as his backups. Maybe even Correa if we fail to get rid of him.
I am pretty certain quality forwards are more expensive and also harder to find but let's say for the sake of the argument you're right. You don't need to have 4 solid wingers. Look at Milan for example. They have a great one in Leao but rest are players like Rebic, Salami guy and Messias.We couldn't play 4-3-3 or 4-2-3-1. Solid wingers are the most expensive players by position I'm pretty sure. Even the shitters go for 20m+
Ok, now I'm depressedDon't let the expiring contracts fool you, we're not going to go out and sign 15 new players to overhaul the squad. Most of these fucks will be renewed because it's obviously cheaper to extend players on lower wages than it is to go out and sign good replacements.
I expect Gagliardini, Handanovic, Dzeko, D'Ambrosio, Darmian, Acerbi, probably even De Vrij and Lukaku to all be here next season - one year older and having declined even further than they currently are.
