Somerset director of cricket Matthew Maynard said:
"I thought the attitude of the team throughout the game was first class. The bowlers did a great job for us, but it showed most in our fielding.
"You expect your younger players to excell in that department, but when the older guys like Tim Groenewald are throwing themselves around to prevent runs it really means something.
"Craig Overton set the tone for us with the ball in both innings. He would have been a tired lad going out there this morning, but still took two wickets with a brilliant aggressiveness.
"A big shout-out to our two spinners as well. We now go to Surrey in a really positive frame of mind, but with a lot of work still to do."
Lancashire skipper Steve Croft said:
"Massive congratulations to Essex. That's eight games they have won, which is an incredible effort, and they are thoroughly deserving winners of the Championship.
"We had a close game against them at the start of the season and a couple of other matches could have gone our way with a bit of luck. But it was a tough task staying close to Essex the way they have been playing and we will take a lot of positives out of the season.
"We didn't bat or bowl well enough in the first innings of this game, but fought back well yesterday and had a couple of things go against us. Now our goal is to finish runners-up. We were written off by many at the beginning of the season, but emerged as title contenders."
