Former Scotland striker Kris Boyd has hailed the impact of Manchester United midfielder Scott McTominay.

Boyd admits McTominay is fast becoming Scotland's most influential player.

He wrote for the Scottish Sun: 'He has been a leader and a warrior for Scotland in every single game.

"Even in Georgia, when things were getting really niggly, he was the one leading the fight.

"And after the game, McTominay was the man who rightly called Willy Sagnol's players “cry babies" for their antics.

"McTominay was born in England but you can tell that playing for Scotland means everything to him.

"On that, a special mention to Alex McLeish for his key role in persuading him to commit in 2018.

"England boss Gareth Southgate was also having a look at McTominay during that period.

"But Alex travelled down for talks with the Man United man and that personal touch paid off.

"McTominay has been all-in with Scotland since making his debut five years ago and Clarke is getting the best out of him.

"It took a while to find his ideal position - he played as a centre-half and also in a sitting midfield role.

"In terms of how fans viewed him, he also maybe suffered from being the Man United star turning up for Scotland duty.

"I remember it with Darren Fletcher. He was playing every week at Old Trafford and people sometimes expected too much of him.

"But McTominay has really blossomed with Scotland over the last 18 months playing in that advanced midfield role.

"It's perfect for him and he has stepped up time after time.

"He has the pace, energy and talent to make things happen and he can also get a goal."
