Philippe Coutinho is a very versatile player
For any ordinary club, signing a versatile player would be a huge bonus, since he would able to play in his usual position and cover in other roles when players sustained injuries. But signing a versatile player is no added bonus for a club like Barcelona.
Barcelona has too much quality for Coutinho to fit in, except for in a fixed position. As to what that position will be, there’s a huge question mark. He is equally good in all the positions he has mastered, but his role will be based on the squad’s needs.
The squad is currently well-stocked in all positions, other than centre-back. The midfield, especially, doesn’t need any new additions. But the left winger position is not occupied by any player other than Gerard Deulofeu, who doesn’t have a spot in the first-team.
If Ernesto Valverde uses Coutinho as a left winger, he would be able to revert to the 4-3-3 formation with full confidence. But there are other options as well, such as, the 4-2-3-1 formation, which would allow both Coutinho and Dembélé to play in their preferred positions.
Coutinho can also play as central midfielder, but Paulinho, Denis Suárez, André Gomes and Sergi Roberto have done a good job of backing up the usual midfield trio. As for the central attacking midfielder role, that is only possible if Valverde switches to the 4-2-3-1. And even if he does, Messi would the favoured player in that position.
But regardless, Philippe Coutinho is a brilliant player, and very soon, he will start justifying his €160 million price tag.
