England manager Hodgson will field an experimental XI on Friday evening when Chile come to Wembley. Adam Lallana, Jay Rodriguez and Ross Barkley will have a chance to impress in one of the three remaining games until Hodgson has to pick his squad for Brazil 2014.
There always seems to be a surprise inclusion or omission in the run-up to major tournaments, but Hodgson threw a shock name in to the hat in the form of 22-year-old Wigan midfielder McManaman on Thursday night.
The midfielder was named man of the match in last season's FA Cup final, but he is now plying his trade in the second tier of English football.
"I can't honestly say I've got 18 names stamped with five more to come. There is a lot that can happen between now and May," Hodgson said.
"We've got a few on the fringes who we look at, like Callum McManaman.
"We were talking about him the other day. He was flying for Wigan at the end of last season and then he got that unfortunate injury, so he's one we'll have a look at.
"We have been following his progress.
"There are certain players like that who aren't out of our radar.
"I would be lying if I didn't say he has a lot to do (to make the World Cup squad), but it is certainly not impossible."
