Crewe Alexandra striker Harry Clayton believes his younger brother Max has the potential to play for England.
Max has been a regular in the first-team squad this season, scoring two goals in 12 appearances for the Alex.
Harry, who is currently on loan at Stafford Rangers, told BBC Radio Stoke: "Max can go all the way and play for England's first team in my opinion.
"He's still only 17. When he grows a bit more and gets a little bit bigger, I think he can go all the way."
Max has been capped at several youth levels by England and recently made his debut for the Under-18 side in a friendly against Slovakia.
At 18, Harry is a year older than Max, but he has yet to feature in a first-team game for Crewe.
However, he is confident that he will be able to force his way into the plans of new manager Steve Davis.
"I think I've got good ability," he said. "All I need is to get experience of men's football and maybe get a bit bigger myself.
"Hopefully I can have an impact in the next couple of years."
