Why Dybala makes sense....
Skill set. What has impressed me the most is not his goal total, but his assists at his age. This kid plays incredibly well around the goal, his head is always up when has the ball at his feet. Morata on the other hand, plays with his head down (drives me nuts sometimes) but is an absolute goal hawk. These two would be an fantastic compliment to each other based on their different styles. Somewhat similar to Tevez and Morata now. In contrast, Morata plays a lot like a younger Falcao, I think their styles may actually clash.
For "unproven" players, the best way to rate them is based on their games versus the best teams in the league. If you watch his games against Roma, Napoli, inter, etc... HE controlled the entire game against some defenders with 7+ years more experience. He had full confidence which is rare at 21. He had a tough game against us, but so has most of Europes best teams, including Real Madrid, over the past three years. This kid plays for Palermo, not exactly talented pieces around him so I do not knock him. Side note... He played a great ball across the 18 against us which should have been finished.
Next, the price. As I read this forum, a lot of you are hung up on transfer costs, but are neglecting wage ramifications. Sure Isco, mata (who both play a different position), Cavani, Falcao, etc would be great, but they would command a $7m - $12m yearly wage . That would cripple any chance of keeping Pogba. With Dybala, we get a confident, young, agressive, kid for a third of that wage. I'd be willing to dish out $30m on transfer for a $3.5m year wage any day. We could realistically keep Pogba with our earnings from all competitions this year and bolster our front. It even gives us flexibility to restructure Pogba for $7m/yr (granted will piss other players off).
You have to look at the big picture... We sell Pogba for $100m ($4m/yr) and we buy 3 good players with that money for $30m each, their combined wages could be close to $21m/yr which is way too much for us. Let's grab Dybala at $30m, keep Pogba , and instead look for new wings with speed that can actually deliver a cross, our current biggest weakness.
By the way, my first post, nice to meet you all.
