Watching Celtic struggle against St Johnstone on Sunday, it became apparent just how much the team were missing captain Scott Brown, who was suspended for the game.
Even though the likes of James Forrest, Kieran Tierney and Moussa Dembele were all on the bench, none of them have the impact that Brown has on the team.
He is the natural leader of the side, who can pull a match by the scruff of the neck and make the Hoops tick.
He is going to be massively important to the Hoops’ chances of progressing against Zenit in the Europa League, which is why it is so important that Brown keeps his cool and controls his temperament in what is likely to be a highly charged atmosphere.
On occasion the 32-year-old’s temper has let him down, most notably in a Champions League match against Barcelona where he kicked out at Neymar and was deservedly sent-off.
It is vitally important that Brown, who is perhaps the most senior player that’s playing regularly in the squad, sets an example for his team-mates to follow.
If he is able to keep his cool and his fellow players do the same, there’s no reason why Brendan Rodgers’ side can’t enjoy a European glory night in Russia.
