The strikers and wide midfielders score more or less the same amount of goals per season in this tactic so I wouldn't place all your bets on the strikers and furthermore I find that the wide midfielders are more important for the tactic than the strikers and I recommend strengthen these positions at first priority.
Btw, I wouldn't call Andrea Belotti "top notch" striker.

He has 128/148 CA/PA at the begging of the game and such CA/PA suite to the mid-table clubs in EPL.
Many of his attributes are at very average level about 13-14. Just look at him...

Heh, I would call someone "top notch" only in case if he had CA no less than 175+ and his major attributes were at 17-18 level.
