"I'd been finding myself repeating to coaches in terms of what we had to do in finals.

Although he was unable to bring in the silverware they craved, Rose has had a huge impact on Somerset's successful youth system.
Jos Buttler and Craig Kieswetter, now England internationals, along with James Hildreth have all flourished under Rose's leadership, while youngsters Craig Meschede, Jamie and Craig Overton and Alex Barrow have all broken into the first team.
Rose will continue working in youth development when he leaves his current role, and he hopes to bring through many more hopefuls.
“It's been a great trip for me. I'll go with sadness but also with a lot of memories”
"From the day I started we had a policy that I'd spend 50% of my time with the first team and the rest of my time watching second team cricket or going scouting, wearing my hat and sunglasses," he quipped.
"You can survive a cycle if you've got good players but if that cycle finishes and you've not got a supply of young cricketers, your club is going to die."
Rose concluded: "The biggest pride I've got is watching Somerset compete at every level from under-11s to the first team. There's been a transformation in how the cricket team operate and hopefully that's the biggest legacy.
"Perhaps someone else can take it on and improve it. It's been a great trip for me. I'll go with sadness but also with a lot of memories, both as a player and a director."
