What went right for Celtic?

After a performance like that, the most important question is, what went right? The most important aspect of the game, was the clean sheet. Dorus de Vries was only called upon to make one save, on the 14th minute, but it was by far the best chance of the game and the keeper did exactly what was required.

The regularity with which the ball left Dorus’ feet and landed on Moussa Dembele’s chest will also have occurred to you. This was the best we have played out from the back all season.

As the game progressed I was getting anxious about how long is left on Kris Ajer’s contract. He’s still a teenager, but what a player! We waited 40 years for a young tier one defender to emerge and then two come along at the same time.

Brendan changed the format, went with a back three, dropped Sinclair, his top scorer and flooded the middle of the park, which allowed Celtic to control the game. Think how many times you saw Callum McGregor in possession and being huckled by one or more opponents, but having an option of a short and easy pass. Contrast this with the complete lack of options we had on the ball at Rugby Park, or even last weekend against Partick.

Olivier Ntcham had his best game for Celtic and was my Man of the Match. He is unrecognisable from the player who arrived from Manchester City in the summer.

Dropping Scott Sinclair from such an important game was a huge managerial decision. Scott was everyone’s Player of the Year last season and a big money deal for Celtic. So far, so ballsy, from Brendan Rodgers, but he opted to give the spare slot to Eboue Kouassi, who has left his teens since Zenit played their last league game, and who many had written off as recently as Christmas.

The flicker of whatever the scouts saw in the 10 or so career games Eboue played before Celtic parted with £3m for him came into full bloom last night. His tenacity, speed and composure on the ball was arresting.

James Forrest sits in pole position for this season’s Player of the Year. Few defenders can cope with his pace and Zenit’s were no different. Despite his positive influence last night, less of our play goes through him than I would like. Due to the peerless Tierney, we have a left-side bias.

Within two minutes it was clear Moussa was on better form than he has been in months (which gives us another issue to ponder). He did not get on the score sheet, but he was an effective out ball, brought others into the game, and played his part on the goal. His late replacement, Odsonne Edouard, looked every inch the €10m player PSG value him as.

And what about the goal. Charly Musonda’s slight frame has looked a tad fragile since arriving on loan last month, but last night was a lightbulb moment. We got to see what all the fuss is about with this young player.

The chance was created near the halfway line, when he drew three Zenit players towards him before igniting the move with a disguised slip to Ntcham. Seconds later, Charly was inside the box to collect a difficult bouncing ball from Dembele and hung it in the air for Callum McGregor. This run was a lung-buster.

Callum had to leap to catch the ball at the top of his chest. With no time to allow it to settle, he needed to position himself for a snapshot. McGregor took the plaudits for his goal, but this was a worthy accolade for a player who was involved throughout but struggled in recent months to find his early season form.

On another day, we would not have got the win we deserved. On another day, we would have lost a goal to Zenit’s only chance, but last night Celtic had all the answers. It was a fantastic performance from every player. We have a squad and a system which is capable and worthy of winning a second consecutive treble, and reaching deeper into the Europa League. And in case it slipped your mind, Gordon, Compper, Hendry, Boyata, Bitton, Ralston, Miller, Armstrong, Rogic, Sinclair, Roberts, Hayes and Griffiths were all missing last night.

We’ll talk about EBT McLeish another time. I’m not letting missing governance standards at the SFA darken my mood.

And Peter, get Kris tied up.
