Aside from the change of formation, there have been some personnel changes since the defeat of Hibs.
Young Senegalese centre-back Ousmane Diao and Korean forward Gue-Sung Cho have recovered from injury and illness, respectively, to regain their places, while Elias Olofsson, who came off the bench at Easter Road for what looked like an imminent penalty shoot-out, has kept his place in goal.
They have spent a bit of money as well. Croatian defender Martin Erlic came in from Bologna £4.4m, albeit he has been in and out of the XI.
Philip Billing joined for a similar fee from Bournemouth, having been on loan at Napoli in the second half of last season. He has started every game since signing, making one of the central midfield berths his own.
Add to that the existing stars, such as young attacking midfielders Dario Osorio and Aral Simsir, both of whom impressed and scored against Hibs, and the prolific Guinea-Bissau international Franculino, who has 17 goals in 24 appearances this season, and you begin to understand why Midtjylland occupy such a lofty position in the Europa League table.
They haven’t lost at home since March, winning 13 of 17 since a 2-0 loss to Brondby, so Celtic’s task is far from a simple one as they look to extend their winning streak under Martin O’Neill.
