Fans of Celtic's bitter rivals were quick to take the bait and respond to the pundit and weren't having any of it - with one supporting commenting that the Thursday fixtures do the Hoops "no favours" after dropping points against St. Johnstone following last week's first leg.
This will be an incredibly tight encounter but I think Celtic have enough about them to come through.
"We know Celtic is a good team with good players, a good manager and we knew it was going to be a hard game".
The hosts have not played since last week's defeat to Celtic but were nine unbeaten heading into that game.
"It would be a huge achievement for us to go through".
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. We knew Celtic are a good team with good players, a good manager and we knew it was going to be a hard game.
Zenit may not be the force that they have been over previous campaigns but they lie second in the Russian Premier League and have experience in the knockout rounds of the Champions League as recently as two seasons ago.
"We know that over the course of the two legs we need to replicate that, but the players are ready for that".
"Of course, we would have liked to have had one or two more goals, but the concentration and our quality in our game was at a very high level". If they play with that aggression, quality and intensity, then it gives us a great opportunity.
The big decision that Brendan Rodgers faces is whether or not to play Scott Sinclair who was on the bench in the first leg.
Brown said: "We're still the underdogs and coming away from home is always hard but you have to believe in yourself". Celtic is a good team, but we are too.
