He slows everything down in attack and makes us much worse as a team with him on the pitch
Yep.
He doesnt work for us the way we are using him. Is not the brightest outside the box and tends to run at defenders and lose the ball frequently. Not in part his fault because he and dybala are forced to track back to look for balls, when he should be at the receiving end of thru passes in the 3/4 and inside the box.
Next year im 100% he (higuain) would be better for us, assuming we are able to assemble a hell of a midfield... but then dybala will continue being the outcast in our formations since we will likely play with wingers to accomodate Higuain. So if i have to sacrifice someone to see Dybala reach new heights at Juventus, then so be it, sell pipa. Dybala will give us more at the long run.
We can win serie A with DYbala and some good wingers anyways, which is the only reason to keep Higuain (league goals). We all know he is not the man to take us to another level on the CL. Dybala is not either right now, but with a proper set up, he has more potential to reach than Higuain which is already starting to decline.
Another important thing, he seems to be the kind of guy who has problems keeping his fitness, because of natural traits of his body. He will have harder and harder time keeping up the workload with every passing season. So if we want to cash in, it should be now.
