Calvert-Lewin should be starting every match until Tosun earns his place.
Niasse does his best work off the bench. Calvert-Lewin is better at holding the ball and dribbling, making him more valuable for the first 60' or so, plus he's nearly as effective at chasing lost causes.
Not for me.
He offers no threat at all. I find it quite depressing with him up top tbh.
Do like him as a player and think he can go on to be a very good forward but he shouldn't be starting games for Everton imo
