Celtic’s decision to take a punt on Craig Gordon in 2014 has undoubtedly paid off. The Scotland goalkeeper’s injury problems kept him out of the game for the best part of two years after Sunderland released him in 2012.
Working as a coach for Dumbarton and training occasionally with Rangers, the free agent was eventually picked up by the Hoops ahead of the 2014/2015 season and has since gone on to make nearly 200 appearances for the club, winning seven trophies in the process.
Aged 35, Gordon still has a few years ahead of him, however, with such a long history of injuries there is never a guarantee over his fitness.
On top of this, several costly mistakes in the Champions League may have led some Celtic fans to question whether he is still the right man to be their number one and has drawn great criticism from former Celtic player turned pundit Chris Sutton on many an occasion.
Here are three potential goalkeeping targets that Celtic could consider as a replacement for the ageing Scotland veteran.
Last time Celtic took a chance on a young English 'keeper who was yet to make an appearance for his parent club, it seriously paid off. Fraser Forster’s arrival from Newcastle saw him grow from a relatively unknown youngster to an England international, so why not take that chance again?
Manchester United’s Sam Johnstone, 24, is yet to make a competitive appearance for the Red Devils, however, has over 130 games in the Championship and League One for six different teams.
Currently on loan at Aston Villa, Celtic could look to sneak a deal for the England youth international, who surely has no future at United, offering the opportunity to win trophies and play in Europe.
David Marshall first burst on to the scene as a Celt, playing 50 games for the club before moving on to a successful career in England and Wales. At 32, Marshall is still in his goalkeeping prime and has a fair number of years ahead of him.
The former Cardiff City Player of the Year is currently at Hull, however, has lost his starting place to fellow countryman Allan McGregor. In search of first-team football, Celtic could offer their former youth product a chance to come home and see out his days at Celtic Park where it all began.
Joel Robles has had a strange Everton career since moving to Merseyside in 2013, frequently finding himself in and out of favour. Having made 65 appearances for the Toffees to date, he has only featured twice this season. With Jordan Pickford as the clear number one at the club, things do not look great for the Spaniard.
Aged 27, Robles is at a crucial point in his career and is no doubt desperate for first-team football. Having impressed during his runs in the team, keeping out club legend Tim Howard in 2016, his services may be worth enquiring over and he is a realistic and affordable candidate for the Celts.
