The Chelsea loanee, who can play in any position between the defensive midfielders and the centre-forward, has been limited to just 63 Championship minutes since joining Huddersfield in January, when he was still recovering from a broken metatarsal picked up in his previous loan spell, at Lokomotiv Moscow.
Despite that, he is sufficiently well-regarded to have kept his place in the England Under-20 squad which has travelled to Poland for tonight’s Elite League match. And Corberan believes the Terriers will start to see the fruits of all the work he has put in at Canalside on his return.
“The period before the international break was one part of his development because he went a long time without playing minutes,” he explained.
“We’ve needed to do some training with him to prepare him well and that can affect your performances in the games if you train too much. He’s not been ready yet to play 90 minutes or be a starting player so we’ve needed to spend more time working with him.
“Now he is going to have a couple of weeks to improve his level.
“His application has been exceptional in every way because he’s a very professional young player.
“If you are a 20-year-old player without that self-demanding it will be impossible to have a (successful) career.”
Hull City goalkeeper Harvey Cartwright, Middlesbrough defender Nathan Wood and Leeds United forward Sam Greenwood are also in the Under-21s squad. Greenwood’s Elland Road club-mate Lewis Bate withdrew with injury.
England play Germany at Colchester United on Tuesday in the same competition.
