Celtic play host to RB Leipzig on Thursday in a must-win Europa League clash.
Brendan Rodgers has fielded an attacking starting 11 over the past three outings, which has seen Celtic yield 13 goals including two 5-0 wins over Hearts and Dundee. But against RB Leipzig, it will be a different story.
The Hoops have played with a free-flowing attack and were afforded time and space on the ball in their last three domestic outings, conjuring attack after attack.
But German Bundesliga side RB Leipzig propose an altogether different proposition. The likes of Bruma and Timo Werner have more than enough about them to put Celtic to the sword.
Rodgers will know his side need to have much more emphasis on the defensive side of the game, as a loss would put their chances of qualifying for the Europa League knockout phase almost at zero.
The defence of Mikael Lustig, Dedryck Boyata, Filip Benkovic and Kieran Tierney in front of Craig Gordon is a strong one, and two consecutive clean sheets with that back four have proven that.
But it is in midfield where Rodgers must make a change. Callum McGregor is deputising for the injured Scott Brown, and he needs a player alongside him able to act just as solid but have the ability to get forward too.
Ryan Christie, 23, has been sensational next to him in recent matches, but the former Aberdeen loanee is far too attacking to play in a deep-lying midfield role such as this against Leipzig.
It must convince Rodgers to drop the Scotland cap despite his strong form, and instead start summer signing Youssouf Mulumbu as he possesses the experience and defensive nous to help McGregor. Otherwise, Celtic remain unchanged.
