Moyes feels the frontman may provide the Toffees defence with a test quite different to those they are used to facing in the top flight.
"That type of centre-forward was probably more prevalent in my day - we had one of them every week," Moyes said.
"I think it is less and less so the case now in the Premier League, so that is what makes it a little bit more unusual. I don't think there are quite as many teams using a big man the way Oldham do.
"But it is part of football and there is no right or wrong way to play. The job is to win, and whatever way you choose to do it, as long as it is within the rules, that is okay."
