"You have to be able to play quality football and to do that, you have to stay calm and retain your emotion in the game, no matter how it goes".
I have to admit Celtic's defensive structure - which had been all over the place - looked excellent last week to go against my prediction that they'd lose the first leg. You never know what can happen in football, it'll be a long 90 minutes and we'll be very disciplined and make sure we take our chances.
"We know that over the course of the two legs we need to replicate that, but the players are ready for that".
A small section of the Krestovsky Stadium will be closed tonight because of a Uefa sanction for racist behaviour from some fans when they played Vardar Skopje earlier in the Europa League.
"Our belief has always been there". If they play with that aggression, quality and intensity, then it gives us a great opportunity.
The match at Celtic Park was Zenit's first competitive fixture since mid-December, owing to the winter break in Russian Federation, but Smolnikov refused to believe that his side lacked match fitness.
"But at the same time we are a good team, the only problem is we didn't play for two months". It is not important to change the players, it is important to change the result.
People might think us Scots are okay with the weather over there, but the conditions are a different level of cold and I'm afraid I'm going for a tough night for the travellers and another Celtic defeat.
"In all of the qualification games we've played since I've been at Celtic it's been important home or away to retain the emotion of the game".
