6. David Ginola
David Ginola made a big name for himself in the 1990s, starting with a very successful spell at Paris Saint-Germain, where he won 4 trophies between 1993 and 1995 and was the linchpin of creativity in the side and had started to become the talk of football, and Celtic were in for him. Ginola excited every Hoops fan by appearing in Glasgow’s East End to begin talks with Celtic, and it looked like a sure thing. The Herald Scotland reported that Ginola had encouraging talks at Parkhead before deciding on a move to Newcastle United just hours later.
5. Brad Friedel
Brad Friedel will be remembered as one of the Premier League’s finest goalkeepers, but his career path could have been different had he signed with Celtic in 1993. The American keeper, who had just been denied a work permit to sign for Nottingham Forest, spent time on trial with the Hoops after accepting Liam Brady’s invitation to train with the club. However, the Celtic manager decided against signing him. It is thought that Liam Brady couldn’t see him offering any competition to Pat Bonner or Gordon Marshall.
4. Olivier Giroud
It was reported by the Daily Record in December 2009 that Celtic were in pole position to snatch Giroud for as little as £2.5 million from French Ligue 2 club Tours. The Frenchman was in sensational form and at the time had scored 14 goals in 17 games. Yet interest in Giroud appeared to wane when the winter transfer window opened, as Tony Mowbray brought in Morten Rasmussen and Diomansy Kamara instead. Giroud then moved to Montpellier.
