Benteke used to bench Lukaku on the national team. I don't think it is silly at all to compare both. Injuries have done Benteke in over the last couple of seasons, but he is just as good of a player as Lukaku. Some might even say a better better talent if not for the inconsistencies of injury.
You know that players improve, right?
Benteke is a level below and older. Lukaku has a higher ceiling.
Also all of these people saying Everton is his level, we haven't seen him at the higher level, so we really can't make that judgement until we see him at a bigger team.
He is already matching and beating numbers and records of CR7 Brazilian Ronaldo and Suarez.
