With the January transfer window just over 24 hours away from closing, only time will tell if Celtic add any players to their squad on deadline day.
The Hoops have signed a number of players on the last day of the January window, some of whom achieved a lot in their time at the club.
Here are three of the best Celtic signings from January deadline days gone by:
The powerful midfielder joined the Hoops on January deadline day 2008. He arrived from Dundee United, and made an impact in a title race that at one stage the Hoops looked doomed in.
In 2008, Celtic knew that they would have to beat Rangers twice in a matter of weeks to have any chance of winning the league title. Robson set the tone for the first game between the sides with a crunching elbow-led challenge on Christian Dailly.
The Hoops ended up winning the title against Dundee United a few weeks later. Robson never hit those heights for Celtic again, and eventually left for Aberdeen, but he was a key man in helping the Hoops win the title.
Signed a year earlier than Robson on January deadline day 2007, the Hoops managed to hold off Rangers to sign the Hearts midfielder.
The player did the simple things in his time at Celtic. He wasn’t fussy on the ball, and found himself a first-team regular in the process.
His partnership with the aforementioned Robson helped to swing the title Celtic’s way in 2008. It was from his cross that Jan Vennegoor of Hesselink scored the winning goal that clinched the title at Tannadice that same year.
Hartley ended up winning every domestic honour in his spell at Celtic. When you consider that so many January deadline day signings can fall to make an impact, Hartley’s time at the club has to go down as a success.
Armstrong arrived on January transfer deadline day in 2015 – which was actually in February – alongside Dundee United teammate Gary Mackay-Steven.
Armstrong made an immediate impact with a goal on his debut. However,
his best season for the club would come in 2016-17, as part of the ‘invincibles’.
He scored 17 goals, and was one of Celtic’s best players in a team that will go down in history. Armstrong’s stay at Celtic was relatively brief in all honesty, as he moved to Southampton in June 2018. Still, for what he achieved in the invincibles season alone he has to go down as one of the nest January deadline day signings.
