Wicktkeeper Steve Snell says Somerset's confidence is high after recording Sunday's second Champions League T20 over Kolkata Knight Riders.
"We weren't given a chance by most of the pundits," he told BBC Somerset.
"But we've knocked over Kolkata twice now and the guys have got a belief that we can beat anyone now."
Snell, who played in the first three games of the competition in India, will now be replaced by Craig Kieswetter, who returns from England duty.
Snell found himself without a county contract at the end of the 2010 season following his release from Gloucestershire.
Having played Minor Counties cricket for Hertfordshire this summer, he was given a surprise call-up by injury-hit Somerset late on in the season.
The 28-year was then included in the squad for the Champions League as cover for England duo Kieswetter and Jos Buttler and played a starring role in the opener against Auckland, finishing on 34 not out from 24 balls.
"The first game went really well from a team point of view and a personal perspective," said Snell.
"It's been fantastic - It's a completely different world to what I'm used to.
"We've been having police escorts, people stopping traffic for the coach and armed guards. It's not quite the same as driving down the M5 to Bridgwater on a Saturday afternoon, that's for sure."
Snell believes his team-mates can keep progressing in the Champions League as long as they do not get over confident.
"Just because we've won the first game in the group doesn't mean it's job done," he added.
"It's foolish to predict and say that they are going to go and win all the games.
"But I think the process is the most important thing in cricket and, if the guys keep fighting and competing, then they are going to be a match for anybody.
"Not getting too confident could be the key but there's no reason that we can't go and win the next game in Bangalore."
