Two soft goals allowed the Foxes to take a two-goal lead at King Power Stadium, but Saints got themselves back in the game through Jake Hesketh just after the hour mark.
Despite dominating the second half, Hunter’s side couldn’t find an equaliser as they suffered their first Barclays Under-21 Premier League defeat in three matches.

, Hunter said: “I’m very pleased with the overall performance, particularly in the second half.
“I thought we started the game well but then conceded two poor goals. We knew exactly what we would be exposed to, and it’s two long balls that we’ve not dealt with.
“I was very disappointed at half time and a few harsh words were spoken. We were in charge, but we were poor in the final third in the first half.
“There’s no point in preparing for a game and knowing what you’re going to be subjected to and then not dealing with it. We had two big blips and went in two-nil down.”
Hunter introduced Josh Sims at the break and Saints were much improved in the second half, but despite Hesketh’s fifth of the campaign, there was to be no deserved equaliser.
“I made a change at half time and Josh changed the game, so much so they made three changes in formation and took their right-back off,” the Saints coach added.
“He was terrific and as a result of his good work we got the goal which was well deserved.
“The second half we created six good chances, and unfortunately not finished them off. The one we did get was a great goal.
“If you compare the two ages, they are a lot older. There were a lot of plus points.
“We would’ve liked to take a point with the performance, but we haven’t. Now we need to knuckle down.”
