The Hoops captain declares that his side are feeling confident ahead of Tuesday's home clash with Juventus, claiming that it is "probably the biggest game of our lives"
The 27-year-old regards Tuesday's clash as "probably the biggest game of our lives" and believes that the tempo in training has increased noticeably as the Hoops prepare for their first appearance in the last 16 of the competition since they were defeated 4-2 on aggregate by Barcelona in 2008.
Brown was also keen to place emphasis on the power of the fans and the newly appointed Scotland captain warns that, with a sell-out crowd behind them, anything is possible after beating the Blaugrana in the group stage of this year's competition.
"We can beat anyone, especially at Parkhead, as the fans play a big part," he told the pre-match press conference.
"We haven't had the best form in the world at home in the league this season but it's definitely a step up in the Champions League."
The Hoops skipper and his team are well aware that they are up against some of the finest players in Europe, especially two-time Champions League winner Andrea Pirlo, a player who Brown regards as "one of the greats".
"He's getting a bit older now, so hopefully we can catch him," the midfielder joked. "He's fantastic. We have to try and stop him from playing his own game.
"Everyone's a threat. They have technical players and the strikers hold the ball very well."
