McTominay has played 14 times for the 'Red Devils' this season and, according to his manager, has certainly shown he is up to international standard.
"We had some players that missed but we had some players that played so, so well," Mourinho told 'MUTV' following his side's 2-0 victory against Huddersfield in the FA Cup.
"Honestly, I think Scott deserves more than what he is getting," the Portuguese added.
Although McTominay was born in Lancaster, the midfielder has Scottish ancestry and believes his international career would be with the Scots.
Scotland haven't qualified for a major competition in 20 years, so new manager Alex McLeish will need to make some inspired changes if he's going to have success with the side. Could McTominay be the man to lead Scotland to the next World Cup?
