The issue I have with PSG's current set of starters is that Ney, MBappé, Gini and on a lesser extent Verratti heavily lean to the left side of the pitch. Hakimi and Messi are the only one really leaning to the right.Diamond/hybrid false 9. So Messi can play the Hook. Neymar plays as the SS who drifts left and if he stays Mbrappe as the ST who drifts right. Which then allows Messi to take the Central role as 10/false 9
Defensively 3412 might be better but if you have Hakimi and Ramos on the right side. That's the side you attack down. Hakimi will do his best Kyle Walker impression and Ramos is Ramos either get pulled out of position or give away freekicks and get bookings.
Also if the rumours are true PSG want to get rid of about 10 players. Most of them will be the midfield workers and back up defenders Ramos Marquinhos and Kimpembe staying injury free for the whole season
Kylian can play on the right but his best work as been as a left winger the past few years and je's been vocal playing on the left so Im not sure he'll put his ego away and play on the right for a whole season. That's why I put Messi on the right and Ney as 10. But we know they will easily swap position in real life.
Not surprised of PSG needing to offload. Waaay too many midfielders in that team, at least 3 need to leave. Icardi needs to go too. Been a dead weight and Messi dont fukk with him.
