Celtic took a giant step towards clinching the SPFL title in midweek as they ran out 5-0 winners on an evening when Rangers slumped to a 2-1 defeat away at Kilmarnock.

What's the word?

With the Hoops storming towards their ninth consecutive title, attention will now turn towards the Europa League clash away at FC Copenhagen next week.

Celtic's most dramatic victory of the season so far arrived in Europe when Olivier Ntcham scored a last minute winner to down Lazio in the Group Stage as Neil Lennon's decision to play 3-5-2 paid dividends.

That formation has been utilised in the league since the turn of the year, but the recent return of Mohammed Elyounoussi has created a conundrum to dissect for the 48-year-old manager.

Ahead of the trip to Denmark, one fan asked The Athletic's Celtic correspondent, Kieran Devlin, how he expects Lennon to approach the game from a tactical point of view, and he claimed he's anticipating a return to 4-2-3-1.

"I think this Celtic team can only really play one way — at least one way very well — and that is to be high-intensity and high-risk. Lennon’s intention will be made clear with the team announcement before kick-off next Thursday but I think there’ll be a return to the 4-2-3-1, with Frimpong and Elyounoussi’s return."

Changing a winning formula

While it's easy to understand the reasoning behind Devlin's point of view, it would be a bold call to alter a system that's been working so well for the club domestically.

It's also worth considering that Elyounoussi has only played 103 minutes of competitive football in 2020 and 85 of those arrived in the SFA Cup against third tier opposition.

To throw him back into the mix in a game of this magnitude and intensity would be a brave move, especially when you factor in a change in system alongside it.

It will be intriguing to see which way Lennon goes in Thursday's showdown.
