I've been a fortunate person to play in some successful teams but I was thrilled with Somerset Justin Langer

Fresh from the county's promotion from the second tier the 37-year-old Australian wants to take Somerset to their first Championship title victory.

"If we stay injury free and continue to build on last year there's no reason we can't win," he told BBC Radio Bristol.

"That's a great challenge and something that's certainly a huge motivation for me at this stage of my career."

Somerset ran away with the Second Division title in 2007, winning 10 matches and losing just one, to finish with a record number of points.

"I've been a fortunate person to play in some successful teams but I was thrilled with Somerset and I was thrilled with the progression the club made," added Langer.

"The way the guys played their cricket was very inspiring. They worked hard, played hard and we had a great time as a result. You have fun when you're having success.

"And to go from the bottom of the Second Division to winning the First Division within two years - that would almost be unprecedented."

The turnaround in form and winning culture made it a no-brainer for Langer when it came to signing a new contract and he is relishing the chance to team up with two former international foes again.

The Australian opener has become firm friends with former England duo Andy Caddick and Marcus Trescothick, the team's premier performers in 2007.

The 39-year-old Caddick, who Langer describes as the "catalyst" to the team's success, made light of his veteran status within the squad to claim 70 wickets at 24.14.

While Trescothick, 32, put worries over his stress-related illness to one side and plundered more Championship runs than any other batsman in the squad with 1,315 at 62.61.

"Marcus was absolutely outstanding," Langer said.

"When I arrived it was obviously very public him leaving Australia and the Ashes in what for a lot of us was the biggest series of our career.

"But I love the way he goes about his business internationally and domestically and his contribution in the clubhouse was just fantastic.

"He's a terrific person, a natural leader and his contribution was immense.

"And if you know you've got an Andy Caddick who's going to keep putting the ball in the same areas, take wickets and be as fierce a competitor as he is makes my job as a captain easier.

"It's so good to have his leadership, expertise and pure skill.

"In my view, besides Andrew Flintoff he's still the best bowler in England. His season last year proved that.

"I'm staggered he hasn't played a lot more Test cricket in the last 10 years. In fact, I'm staggered he hasn't played every Test for the last 10 years, that's how highly I rate him."
