Negatives:
[B]- not an explosive player;
- not very strong to hold on the ball;
- doesn't really beat his man often on driblle or acceleration/pace;[/B]
- huge reliance of left foot, something that limits his performance a lot;
- not a great finisher due to no use of right foot.
It's hard for me to watch his performance against Bolognia and Sevilla and walk away with the impression that he can't beat a man or lacks acceleration/pace. The Bolognia video of all his touches (there is one of him vs Sevilla) show how he creates by dribbling either past players or sucking them in which opens up space for an incisive pass.
See here (you will find his Sevilla video as well on that channel).
See 20 seconds
Also see in the third minute on the pass to Cuadrado. 3/4 Bolognia players get sucked into covering him which opened up the space in behind. Zaza's goal vs Sevilla was a result of Dybala settling a difficult ball, beating one person, and then slipping a pass over to Zaza before getting tackled by a 2nd Sevilla player. Zaza is able to run alone on goal because Dybala eliminated two defenders on the play.
Throughout these last two matches you will notice how well he keeps possession since he so often essentially becomes an offensive midfielder by drifting into pockets of space between lines. He is excellent in doing that. What I agree with is that he isn't strong enough to hold up the ball when he receives an aerial pass or is posted up with a CB on his back. That is understandable and shouldn't be his job. Morata's better at this obviously due to his strength.
With that said, I do agree that he relies a lot on his left foot. The same was said of Messi. When your one foot is that good and you play in a balanced formation then this isn't as much a problem at all.
As for his lack of scoring, with Morata moving from the top left to the center of the formation as a true CF, Dybala moves into the midfield. In this partnership, he isn't really a striker but a supporter/offensive mid. When Dybala plays as a lone striker, he has shown to be a good finisher. He isn't asked to do that right now and his duties as a creator are more important given the scoring form Morata is in. Plus, Allegri wanted a trequartista and he got Dybala and Cuadrado as creative outlets instead. Not bad!
