Its all opinions of course on what he would or wouldn't have gone on to do but I just think like a Coutinho or a Bale with us under AVB he thrived because of the system he was in where he basically could do and try anything he wanted due to the severe lack of attacking quality around him and a club that was annually struggling for their top flight lives. Has Coutinho suddenly become a rubbish player? No, its just that in Spain he wasn't the guy in the team that the ball consistently went through. He wasn't the guy that took all the set pieces and with players around him like Messi, Griezman, Suarez, Dembele and a manager that asked him to do a role in left midfield, all of a sudden he looked a shadow of the player he was at LFC. I think LeTissier would've gone the same way once he left and I think deep down he knew it too and thrived in his new founded freedom where he was able to express himself fully and through that his finishing (which was exceptional) thrived. Never under estimate the role systems can play in inhibiting talented players and vice versa (in reverse see Zaha at Palace vs Utd......100M player now lmao)
