Tribute to U's supporters from departing forward.
Immediately after his move to Leyton Orient was finalised on Wednesday afternoon, he spoke to the official website to offer his thanks.
"We have been through some tough times over the past few seasons but the fans always stuck with us and gave us their full support," he told the club's official website.
"It looked like we were going to be relegated weeks before the end of the season but they still came to cheer us on thinking we could survive again.
"Even on the final day, when we had the lap around the pitch, it was evident that the fans were right behind us and they deserve a brighter season next time round.
"I'd like to say thanks to all of them for the support they gave me personally in my time at the club, it has been much appreciated and will not be forgotten."
There was also thanks for the club for giving him the regular football he craved, having moved from Watford as a raw nineteen year old in 2012.
He made eight appearances on loan in the 2011/12 season before signing permanently in August.
His four seasons saw him average over forty games a season, certainly enough to warrant the tag 'regular'.
He said: "I came here wanting to get regular football and that has certainly been the case in the four seasons.
"Thanks must go to John Ward for signing me and to him and the subsequent managers for giving me the opportunity to play so many games in my time at the club."
Finally, Gavin spoke of the move to East London, saying: "It is a chance of a fresh start for me and the club. It has been a tough few years and the move feels right for me at this time in my career.
"I hope to play as regularly as I did at Colchester and obviously want to help Orient get promoted.
"If Colchester are up there as well at the end of the season, all the better."
