Norwich City captain Russell Martin has revealed he urged former Canaries' assistant boss Colin Calderwood to sign up highly-rated Scottish international defender Andrew Robertson.

The duo are in Gordon Strachan's Scotland squad preparing for upcoming Euro2016 qualifiers against Georgia and Poland, with Robertson already impressing at Premier League Hull City this season since his £2.85m summer switch from Dundee United.

Martin admitted on Monday he was quick to spot the potential in the exciting left-back, so much so he made a point of tipping off former City boss Chris Hughton and his backroom team.

'Andy has done great. I told our assistant manager at Norwich last year that he should sign him after seeing him in one session up here,' he said. 'He looked a fantastic player and has adapted brilliantly to the Premier League after signing for Hull. He is playing with international players who have been in the Premier League for a long time and that will only help to bring him on. He is going to be a big player for Scotland in future years and possibly now. He loves to get down that flank and has got a great delivery. That is a strength of his.'

Robertson missed the opening qualifying defeat to World champions Germany through injury but could return for Saturday's Hampden tie against Georgia at the expense of Martin's Norwich team mate Steven Whittaker. The Canaries' captain is in line to continue at the heart of the Scottish defence after forging a solid central defensive pairing with Blackburn's Grant Hanley.

'I enjoy playing with Grant. He's strong and quicker than a lot of people think,' he said. 'He's powerful and likes to attack the ball, so I like to go in behind and sweep up after him. I think it works well.'
