If he scores 10 goals in the PL it will be a super successful season.
I definitely agree with this. 10 is a good goal, although I wouldn't be surprised to see him net around 15. He's proven that he can finish with good service, and I think Sunderland is putting some really nice pieces together.
If Jozy were able to score for the Black Cats at the same clip he scored at for AZ, he would net 21 goals just in PL play.
Now of course we all know that won't happen, so I do think 10-15 would be a fairly solid prediction.
