Selling him now would only lose alot of money.
Try him at first at CM.
He is doing too much stationary dribbling nowadays.
I start to believe that even at CM or CAM, whatever position you want, he'll flop. Guy is just a moronic player. Some used to doubt Dembélé's intelligence, well Coutinho is even dumber of a player than worst teenager version of Dembouz, without having Dembele's athleticism.
Coutinho holds on the ball way too long, doesn't see or intentionally snubs great passing opportunities, and is so weak on his feet. And to top it all, he's as lazy a player as you can get.
Under this board and under this coach, the only possible conclusion for him at Barça is to be a flop I fear. So we need to sell him ASAP. Anything above 100m is a blessing for Barça right now.
