Celtic greats Jim Craig and John Clark have urged the next Scotland manager to play rising Hoops star Kieran Tierney in his favoured left back position for the national side.

Lisbon Lions Craig and Clark, who were at Hampden last night to be inducted into the Scottish Football Hall of Fame, were both united in their belief that Tierney is the best man for that position.

In the ultimately unsuccessful World Cup qualifying campaign, Gordon Strachan played Tierney on the right hand side to accommodate Liverpool left back Andy Robertson.

Having impressed initially in the right-back slot, Tierney’s effectiveness was nullified somewhat in the key double header against Slovakia and Slovenia.

And Craig said: "I never think you play as comfortably on both sides. Tommy Gemmell wasn't half the player at right-back as he was at left-back and Danny McGrain wasn't either.

"I think you are more comfortable in the one position.

"You can see someone is comfortable. Stuart Armstrong this season is looking more comfortable than he was last season because he has been allowed to play in a position he likes.

"It is a nice problem if you are still getting your cap. I think it is not possible to play comfortable both halves of the pitch. You are more comfortable playing in the one you have been picked in. I think the best player in the position should be picked so I would play him."

Clark, who earned four caps for Scotland, added: “He is playing in his natural position, he can get good balls in. But if you play on the other side you have to switch round all the time.

“I think Tierney is the best left-back. If he has competition from another player then it is good for him, it is good for the players trying to get in as well, pushing each other.

"I think he has more strength and aggression about him than Robertson. Robertson is a good touch player but I think the young player Tierney is aggressive as well. He can get forward and hits in decent balls but on the right side you have to turn in on to your left foot and things are closed down."

In the 50th anniversary of Celtic’s 1967 European Cup triumph, both Craig and Clark have been in-demand figures during a year of celebrations and festivities to mark the club’s greatest conquest. Craig still remains amazed that the success continues to resonate through the generations.

He said: “This is my 28th function of the year. I’ve been to Las Vegas, Portugal, Ireland and all over Scotland.

“It’s been quite remarkable. What has surprised me through the years is just how many people know about the Lisbon Lions.

“My grandaughter Ella lives just outside Cardiff and went to visit her pal next door. The wee girl’s dad James asked Ella what her grandfather did.

“She said he used to be a footballer won the European Cup with Celtic and he knew all about the Lisbon Lions so that gives you an idea of how far we reached.”
