If you noticed, even after Dybala came on, Morata remained as the "LWF", and Dybala occupied Mandzu's spot as a bit of a false 9. And in the spell they were on together the two interchanged positions several times, even leading to Morata being over to the right edge of the penalty box when he took his goal.
I love this. Everyone rants and raves about Barca's attack, and Madrid's attack, and those teams have the same deal going on often. Messi-Suarez-Neymar fluidly interchange positions frequently, or load up one side, or the centre when it benefits them. As do Bale-Benzema-Ronaldo. I've seen Bale all the way on the left touchline before, making runs with the ball.
A front 3 of either Cuadrado-Mandzu-Morata or Cuadrado-Dybala-Morata would be brilliant. Dybala and Morata will frequently be drifting in and out of the centre. It will be like having a False 9 and a Wide 9. The amount of pace, dribbling, ball-skill in that second incarnation with Dybala would be immense. If Morata and Dybala keep developing into top/world class players, we could be looking at one of the best attacks in the world with those 3.... And then think about adding Berardi to the mix.
+ The other funny bit on that goal is all 3 of our attackers are on the right side. If you look at the video Dybala is trailing in from behind on the right. People get way to caught up with this idea that if Morata or Dybala is on the wing it will waste them because they'll have to remain wide all match. It's simply not the case, and never will be. Morata will be asked to defend the left side, but by no means will he be restricted to it going forward as evidenced by the match.
