Because quite frankly it is just a waste and alas for his ability. To have the physical features he has, which allow him the chance to find the space to cross, and then produce the horrible crosses is a really sad thing. Just like a writer with great rhetoric ability writing utter frivolous things. Abate should seriously work on his crosses because they are his final product in his attacking game mostly. His delivery is what decides if his efforts amount to something. He battles and runs forward only for all that hard work to go to waste most of the time due to his poor pass. Just like a super car with a monstrous engine, but handles poorly. You got all this power that you can't do much with and that is a real pity.
The coaching staff should and Ignazio himself should work tirelessly on this because we have a diamond in the rough here. We already have the diamond, hence, it is complete ignorance not to refine it.
