West Brom academy manager Mark Harrison has revealed that youngster Jonathan Leko is his own harshest critic.
The 17-year-old has progressed through the Baggies’ academy system and made his professional debut last September in the League Cup.
Leko was handed his first Premier League appearance in April and went on to feature five times in total through to end of the campaign.
The forward was subsequently rewarded with a new contract at the Hawthorns and is now tied to the club until the summer of 2019.
Harrison, who has worked heavily with Leko, revealed the teenager is very critical of his performances and always wants to improve.
The academy chief says Leko hasn’t allowed his progress to go to his head and insists he has remained humble.
Harrison said: “He critiques himself very well. He beats himself up a little bit and it’s our job to give him that balance.
“He’s very critical as well, so when he reviews himself he tells us ‘I could have done this better, I should have done that better.’
“I just tell him to get on with it, don’t get carried away, you’ve got to continue to work hard.
“He hasn’t changed yet and, touch wood, hopefully he won’t. That’s our job to make sure we keep nurturing him.
“He’s very well nurtured, there’s no edge to him. He’s got a humble side to himself.”
