Hull City academy coach Stephen Clemence is delighted seeing Max Clark in the England U18 squad.
But Clemence knows the young left-back must keep on improving.
"It's a great achievement for Max to get called up to the England under-18s for the first time and it helps continue his progress," Clemence told the Hull Daily Mail. "We're all really pleased that he's been recognised. Max trains with me in the development squad every day now and done very well.
"He still has a lot to work on and still makes mistakes in pretty much every game he plays, but that's understandable given his age playing against older players. The important thing is that he's willing to learn and he's definitely impressed me.
"We're hoping in the next year or two he can kick on even further but to do that he knows he's got a lot of hard work ahead of him."
