Lets keep it simple for everybody to understand
If you have 6 midfielders+attackers and they are 9/10 dribbelers, and lets say two 8/10 passers.
You are gonna bench 1 or two of those 9/10 dribbelers, because you need to mix them in with a playmaker or two.
When Tevez was the SS, we had a player that could take the ball and keep it+distribute it in the final third. Having Pereyra behind that was fine.
With Tevez gone, we are lacking a player that can do this. Dybala isnt a playmaker, he's a creative forward. If you demand him to keep the ball and distribute, you take away a good part of his game, simular to how Pogba is alot of wasted as a trequartista.
With the current formation, Vasquez would suit this team very very well. He's entirely different to Pereyra. He's a more static player, who's all about getting passes and distribute it, and can combine reall well with Dybala.
Maybe making it even more easy, is more clear for you
Imagine a 4231. Imagine the striker beeing fastpaced moving into channels. Imagine the 3 cam's beeing dribbelers. Who will distribute the play ? No one, they all are best at taking on players. You take out 1 drbbeler and replace him by a playmaker that is overall perhaps not as good, but he'll make the team work ALOT better
@Red do you think i put it simply enough for the statistical majority of 'tuz to understand ?
