Oliver Burke and Kieran Tierney hailed as future Scotland stars by Pat Nevin

Scotland may be struggling in World Cup qualifying, with manager Gordon Strachan under pressure ahead of Friday's match with England, but former winger Pat Nevin believes they have two future stars in Oliver Burke and Kieran Tierney.

Burke, 19, became the most expensive Scotsman in football history when Leipzig paid Nottingham Forest a fee of £13 million for him in August. The east German club lie second in the Bundesliga, with the winger featuring in eight of their matches so far, scoring once.

Strachan has Burke in his squad for Friday's Wembley assignment, though Celtic's Tierney is absent as he recovers from ankle ligament damage suffered last month in training.

Burke is likely to be a substitute in London.

Nevin, a former Chelsea and Everton winger who played 28 times for Scotland, told ESPN FC of Burke: "The raw material is absolutely there. He's got mad pace, [Gareth] Bale-like pace, a good physique, some skill, but I've not seen the game awareness yet.

"If you are going to make an impact at the highest level that's something that will have to be developed. I think he's made a great call to go to Germany. He could be a very special player though note the word 'could.' It's never definite. Whether he can shred England I am not convinced."

Left-back Tierney, also 19, shone during Celtic's 3-3 home Champions League draw with Manchester City in September, making the overlap which caused a Raheem Sterling own-goal.

"He is quite capable of playing in the Premier League and I don't say that lightly," said Nevin, before comparing Tierney to a Scotland and Celtic legend of the 1970s and 1980s.

"I liken him to Danny McGrain and there is no higher praise than that as far as I am concerned."
