Billy could go on and win more caps than me.. he's my little brother

THEIR relationship on the pitch is clear at the heart of Scotland's midfield.

- 

And off it, Scott McTominay says his Napoli pal Billy Gilmour is now more like a little BROTHER than a team-mate.

The pair are part of a four-strong Serie A contingent in Steve Clarke's national squad, along with Lewis Ferguson and Che Adams.

But with McTominay and Gilmour starring for the Naples title-chasers, they're Scotland's poster boys in Italy.

The duo have always had a good understanding of each other's game in a dark blue shirt.

But teaming up with Gilmour in Napoli's sky blue has strengthened their bond even further.

They've grown closer to each other away from football-but McTominay remains in awe of his midfield sidekick's ability.

The former Manchester United star will earn his 60th cap for Scotland tonight at Hampden against Greece in the Nations League play-off second leg At 28, he could conceivably go on to break the 100 barrier and get close to Kenny Dalglish's record of 102.

But McTominay rates Gilmour so highly that he expects the ex-Chelsea kid to get even MORE than him.

Both players were terrific again for Clarke's side in their 1-0 first-leg victory in Piraeus on Thursday night.

And ahead of the return, McTominay heaped praise on his Napoli pal. He said: "Billy is such a great player.

"Whenever he has come into the team in Naples, and when he has played so much for Scotland, he has been a breath of fresh air.

"He's technically gifted and makes a difference to the team because he is so calm on the ball.

"We've a really good relationship.
