I think the point is that Morata had a much better season than people are giving him credit for. 12 goals - 11 assists in 2377 minutes. A goal or an assist every 100 minutes basically. And that's with an awful 3 month slump in the middle of the season with almost no production.
He had more assists than Dybala. Second on the team to Pogba. He grew by leaps and bounds as a playmaker this year. Next year, I'd bet we will see him be much more consistent, with a more settled team. And I think we'll see him score much more frequently.
He was in awful form from October 18th to January 24th... 0 goals - 3 Assist in 20 appearances (900 minutes)... It was awful.
But he finished the season in absolutely scintillating form. And with how the team finished, and how he finally seemed to figure out his place in the team and get his confidence back entirely, I'd expect him to continue that into next year.
Last 20 appearances - 1035 minutes - 9 goals - 7 assists. that's goddamn brilliant form. A goal or assist every 65 minutes.
