Celtic assistant manager John Collins has told the club's official website that he's been 'amazed' by goalkeeper Craig Gordon.
Gordon, 32, has been a mainstay of the Celtic side this season, making 42 appearances in his debut season as a Bhoys player.
His path to Celtic Park stardom has been a remarkable one. The former Hearts stopper was one of the brightest goalkeepers around when Sunderland bought him in 2007 - but his career in England ended in disaster.
Gordon was released after five years on Wearside after a spate of injuries, and Gordon ended up taking two years out of football after his Sunderland exit in 2012.
Yet last summer, Celtic offered him a route back into football, and he signed as an understudy to first-choice goalkeeper Fraser Forster - before being thrust into the limelight when Forster was sold to Southampton just a month later.
Now, Gordon's injury problems appear to be behind him, and he's been one of Celtic's best and most consistent players over the course of the season.
Back in the Scotland fold, Gordon could face Northern Ireland on Wednesday night for Gordon Strachan's men, and Celtic assistant Collins heaped praise on Gordon in an interview with the club's official website, saying that he could yet play on for a number of years given his attitude and work rate at the club.
"Craig’s been an incredible signing," said Collins. "In all honesty, he’s surprised and amazed everyone, not that he’s a great goalkeeper, but that’s he came back so quickly to what he was before after being out for over two years. From his first game, he has never looked like he has been away."
"He’s so calm, composed and is assured, and he just spreads confidence throughout the boys in front of him. He’s a great example on the training pitch. And that’s someone that is 32. Goalkeepers can go on 'til their 40, so hopefully he has plenty of years left. He is lean and fit and week in, week out, he plays to a very high standard," he added.
