Celtic have been linked with their fair share of big name players over the years.
Here's a list of 15 footballers who were linked with Celtic but never actually signed.
Italy and Juventus legend Del Piero was close to moving to Parkhead in 2012 but opted for a move to Australian club Sydney F.C. instead.
Martin O'Neill tried to sign Rivaldo in 2004 when the Brazilian was 32 however the wheels soon came off when Rivaldo discovered he must complete a trial period before the club would offer him a contract. He joined Olympiacos F.C. instead.
Neil Lennon had just been given the manager's job at Parkhead on a permanent basis in the summer of 2010 when he attempted to sign Sol Campbell. Campbell has since admitted he was close to joining and expressed regret for not doing so.
The Wigan Athletic star was almost snapped up by then Celtic boss, Neil Lennon, in the summer of 2010.
Neil Lennon was reported to have approached David James around about the same time he expressed an interest in signing Jimmy Bullard and Sol Campbell.
Barton had expressed a desire to join Celtic after leaving Burnley F.C. in 2016 but when that did not materialise he signed for their arch rivals, Rangers, instead.
It is believed Drogba approached then Celtic player, Mo Sylla, in 2004 to express an interest in a move to Glasgow however Sylla reportedly put him off the idea telling him he would struggle to get first team football.
The England international is another player who has expressed regret over not joining Celtic, once under Martin O'Neill and a second time under Neil Lennon.
The Scotland international forward was targeted as a possible signing in 2016 but joined Sheffield Wednesday instead.
The Daily Record reported in 2009 that Celtic were leading the race to sign Olivier Giroud from Tours for as little as 2.5m however the player remained in France and signed for Montpellier.
Former Celtic boss Liam Brady brought Friedel to Parkhead in 1993 for a trial but didn't think he would offer competition to then goalkeeper Packie Bonner. How wrong was he?
The story goes like this... Ginola had agreed terms with Celtic in 1995 but when Newcastle United came in for him he used Celtic's interest to secure a better contract with the Magpies.
Lafferty, a lifelong Rangers fan, was linked with Celtic in 2008. The Northern Ireland striker said he would relish a move to Parkhead but decided to join Rangers when they expressed an interest in him.
Jelavic attracted the attention of Celtic in January 2010 but after their 2.5m bid was rejected by Rapid Vienna, Jelavic went on to score even more goals. He arrived in Glasgow in the summer of 2010 and signed for Rangers instead.
Hitzlsperger joined Celtic on a two week trial at the age of 18 when he was released by Bayern Munich however Celtic didn't offer him a contract and he signed for Aston Villa instead.
