Celtic captain Callum McGregor has already achieved a wide array of success in green and white, including a remarkable quadruple treble and historic nine-in-a-row. One facet that has continually evaded the skipper, however, is European prosperity.

For many years, Celtic have faltered on the continental stage, whether falling in the Europa Conference League to Bodo-Glimt or losing out in Champions League qualifiers to the likes of Cluj and Ferencvaros.

This season, however, a switch seems to have flicked. Brendan Rodgers’ men are competing in European football’s premier club competition and are just one win away from reaching the knockout stages.

For McGregor, leading his side into the last-16 play-offs would rank highly among the wide domestic success he’s achieved with Celtic: “It would be right up there,” he said (Glasgow Times).

“The last few years have not been great. But it’s a big competition, and there are a lot of teams spending a lot of money. This is where the club wants to be and you’ve seen over the last couple of years we’ve made strides, which is good.

“To the point where you’re going to Zagreb and you’re a bit disappointed when you come off with a point. It shows the growth of the team and the squad and where the club wants to be.

“It’s a big challenge but it’s something the players really do enjoy and want to keep getting better.”

All Celtic need to do to reach the promised land is beat an already-eliminated Young Boys side at Parkhead in January.

They officially went out of the Champions League after losing 5-1 to Stuttgart last night and remain rock-bottom of the league phase.

Rodgers and Co. will fancy their chances against the Swiss outfit, but before then, all attention shifts to domestic matters and Sunday’s colossal cup final against Rangers at Hampden.

The Bhoys will relish the opportunity to secure their first piece of silverware of the season and look to inflict more pain on their city rivals.
