Celtic's 1-1 draw with FC Copenhagen was a quintessential example of a game of two halves as Neil Lennon's decision to revert back to 4-2-3-1 paid dividends for 45 minutes and little more.

The second half of proceedings was effectively a mirror image of the first half only the roles played by each side were reversed. It was if the European clash was following a linear pattern from total Celtic domination to complete Copenhagen domination, abiding to the rules of the pre-match script which was written for each side to adhere to.

There was little argument that Odsonne Edouard's sumptuously lofted opening goal was thoroughly deserved as Callum McGregor provided another assist to take his tally to 10 for the season.

It was a strike that left Lennon gushing over the quality of the build-up and also the individual contribution of McGregor on the night, per Celticfc.net.

“It was a brilliant move for the goal, nice and slick from Ryan Christie and Callum McGregor, who I thought was brilliant again tonight. It was a beautifully-weighted pass into Odsonne's feet and it was a class finish from a class player."

The 19-cap Scotland international's performance, however, was alarmingly mediocre at best and unsatisfactory at worst.

He collected the ball in prime position to hurt the Danish giants before providing the killer pass for the crucial away goal, but there was a distinct lack of involvement from him thereafter.

Though McGregor is an attacking-minded midfielder by trade his lack of defensive involvement last night was telling.

He failed to win one of his four duels in midfield while he also didn't record a single tackle or interception, per Sofascore.

Defensive qualities are not fundamental aspects of the 26-year-old's repertoire but, given Copenhagen's dominance in the second-half, every Celtic player from Edouard through to Forster had something to contribute in their bid to contain the threat posed by the hosts.

McGregor was far from a liability and he showcased his relative reliability in possession by maintaining an 84% passing accuracy and losing possession just nine times; by comparison Olivier Ntcham lost possession on 18 occasions and Jonny Hayes a whopping 22.

And, naturally, it is impossible to discount the invaluable role he played in facilitating Edouard's vital away goal, but that aside there is little evidence to suggest he was as brilliant as Lennon suggested in his post-match verdict.

One of the poster boys of Celtic's academy needs to dig deeper at Paradise next week to ensure they see the job through.
