Everton are split over the prospect of John Stones being selected for England's World Cup squad.
Everton boss Roberto Martinez says Ross Barkley and Stones would be ready for Brazil if called.
"If he decides the youngsters are to be called up to the World Cup, I can guarantee you they are ready," Martinez said. "John Stones has shown he is in a very good moment of form and at a very good level.
"Character-wise, I can guarantee anyone that he is ready to embrace whatever challenge comes his way.
"The truth is that the young players have had a huge role.
"You need to judge players by their performances. The age shouldn't affect the role of a player in a national team.
"Players like Ross Barkley and John Stones have been playing beyond their years and their performances have been of a calibre whereby you know they will help, whatever team they represent."
Everton defender Sylvain Distin is not convinced it would be the right thing for Stones, though.
Distin, quoted by the Liverpool Echo, said: "Stonesy has only played half the season for us and even though he's a special talent, we need to let him mature and not put pressure on his shoulders now. It's way too early.
"Stonesy has been amazing since he started playing for us, that's for sure. But it's a bit too soon"
