Callum Gribbin is happy with his progress at Manchester United this season.

Academy chief Nicky Butt took charge of the Under-19s in the UEFA Youth League last season when Gribbin was still refining his game.

A stellar hard-working display at Wolfsburg helped earn a 2-0 win and praise from Butt afterwards, who felt the midfielder had enjoyed a "light-bulb moment" in terms of adding endeavour and defensive responsibility to his natural attacking flair.

"People came up to me after the game and said I'd worked hard," Gribbin told ManUtd.com. "I was really pleased as it showed people can trust me. So I think that match set me up for the season and going forward as I had to do that other side.

"Everyone was buzzing with me afterwards but, when it's coming from Nicky Butt, it means even more. I think he's a great person. I didn't think he'd be like he is with us but it's an amazing experience working under him, considering his background and what he has done in the game.

"He is honest and tells you when you are doing well and doing badly too. I mean it's not all nice and if he doesn't tell you what you're doing wrong, you are never going to learn as that is what it's all about."
