John Hartson has encouraged Celtic fans to “enjoy the ride” after their Champions League draw was announced.

Celtic were drawn in an extremely testing group against Barcelona, Manchester City and German outfit Borussia Monchengladbach.

The draw was not kind to Celtic but they will play each side home and away as they try to progress from the group stages.

Former Celtic player and now pundit Hartson has posted on his personal Twitter account that the Scottish champions should enjoy the competition despite the difficult opposition.

Celtic have faced reigning Spanish champions Barcelona in the competition before, notably when they pulled off a famous 2-1 victory at Celtic Park in 2012.

The 2012-13 season was the last time Celtic progressed from the group stages of Europe’s elite club competition, when they were eliminated by Juventus in the last 16.

Former Barcelona manager Pep Guardiola is now at the helm of Manchester City and they are likely to be equally as tough an opponent.

Celtic and Borussia will be expected to fight for third place in the group, who earn a place in the Europa League qualifiers, but both will aim to cause a shock upset and eliminate a big contender for the competition.

Brendan Rodgers’ side had to defeat Lincoln Red Imps, Astana and Hapoel Be’er Sheva over two legs just to reach the group stages and will hope to cause an upset and continue their Champions League journey.
