Bruce said: "I don't mean it disrespectfully to Gary and Phil [Neville] and to Nicky [Butt] and to Paul [Scholes] - and David Beckham was amongst them too - but the one absolute certainty when we first saw him play was Giggsy.
"He was the only one I could ever see, hand on heart, and say 'He is going to be a superstar' because it was effortless for him, even as a 14 or 15-year-old.
"He was playing with us in training sessions and I remember him murdering Viv Anderson in one particular training session when he was a kid at 15, and Viv was England's right-back.
"He was such a natural runner, such a natural mover, such a wonderful dribbler with the ball.
"It was all so easy for him, so natural. It made him the outstanding player.
"But there's also the mentality thing. To go and do what he has done from being a boy is nothing short of remarkable."
