Celtic midfielder Scott Brown has backed his club team mate Callum McGregor to “thrive” on the international stage for Scotland after the young midfielder was called up to the squad, according to a report on the Daily Mail.

The 24-year-old is replacing Brown in the squad after he pulled out through injury alongside Stuart Armstrong.

“He has shown up on the big occasions for Celtic in the Champions League, semi-finals and cup finals – he has been there and done it, and he will thrive if he gets the chance to play,” said Brown.

McGregor will be hoping that he can make his Scotland debut as they prepare for two huge World Cup qualifying games against Slovakia and Slovenia.

The Scots need to win both matches to stand a chance of qualifying for the tournament next summer.

“Every day I see his work-rate in the gym and what he does away from football. He is an honest boy and he deserves to be the in squad and he will have shown his qualities in training this week,” continued Brown.

McGregor will be pushing for a start but faces stiff competition from Darren Fletcher, James Morrison, Barry Bannan and John McGinn.
