Scott McTominay will stride out at the Nou Camp tonight looking to complete another Champions League rescue mission against Barcelona.

But his fellow Scot who helped set him on the way to Manchester United stardom as a tiny five-year old will still see the little kid he first worked with on the pitches of Preston.

Dundee-born Charlie Jackson, co-founder of Matrix Soccer Academy in Clitheroe, was head of the Red Devil’s North West Development Centre when he first encountered McTominay.

The 49-year-old knew even at that age the midfielder was a special talent and he has been proved right after breaking into the first team at Old Trafford and winning seven Scotland caps.

But it was against five-time European champs Barcelona where he showed he can really cut it against the best despite a 1-0 quarter-final first-leg loss at Old Trafford last week.

McTominay earned rave reviews from current and former gaffers Ole Gunnar Solskjaer and Jose Mourinho as well as Rio Ferdinand as the 22-year-old was picked out as United’s best player.

He will now have a key role as United look to repeat their heroics from the previous round against PSG where they also came from behind to progress.

Jackson who was with McTominay on the day he signed for United, was at a coaching convention in Qatar when he watched McTominay strutting his stuff against Lionel Messi and Co and beamed with pride at his performance.

He said: “Nothing’s changed – he hasn’t changed. It’s weird but I can still see Scott as that little kid with me in Preston now and it will be the same even when he’s running about in an iconic stadium like the Nou Camp.

“I was in Qatar for the first leg but I made sure I watched the game and I texted his dad Frank who I get on really well with. It gives you so much pride when you see these players make their debuts and then kick on and to have Lionel Messi in his pocket – which he did – is just remarkable.

“I hope he makes it and I’m sure he will because he’s got Manchester United in his blood now. I signed Scott and 17 years later he’s still there – the longest serving player at Old Trafford – and that gives me so much satisfaction.

“I went to Hampden to see Scott make his Scotland debut against Costa Rica. We keep in touch but I speak to his dad more because I don’t want to hassle him.

“His dad always says to me that the best time they had was with us and he gained so much. It was fun and Scott’s a really good lad.

“He is one of the nicest kids I’ve ever worked and he’s got the best parents, his dad Frank and mum Julie are the most down to earth people.

“They are so grounded and that is important because they have made Scott what he is and he hasn’t changed one bit. He’s the same – determined, enthusiastic and honest.

“I was at Manchester United’s Cliff training ground on the day he signed for the club. Every club in the north west fought for the best kids but Manchester United were the biggest then.

“Scott was selected by our representative scout at the time, Steve Done, and was with us from the age of five until he signed for Manchester United at Under-9 level.

“He had been spotted while training with a team called Halton Hotshots and we had him at our centre for almost four years.”

Jackson left Tayside at an early age but is still fiercely patriotic and was delighted when McTominay chose to represent Scotland.

The midfielder was born in England and even met Gareth Southgate but Alex McLeish won the battle.

Jackson said: “I was delighted when he chose Scotland and I took one of my friends to Hampden to watch his debut and he said ‘I wish he’d chosen England!’.

“I moved to England from Dundee when I was five and I hit it off straight away with his dad because of the Scottish connection.

“His dad hasn’t lost his accent at all so he gives me a bit of stick because of my Lancashire twang but it’s all good fun.”
