Houghton joined Chelsea at Under-8 level and won the FA Youth Cup with the Blues in 2014 but did not play a senior game for the club before he was released in 2018.
However, he feels positive about the experience he gained in our Academy.
"I look at it from a glass half full perspective. I had 12 or 13 years there and had an education, I was learning and growing into a man," he told Sky Sports.
"I had amazing opportunities and memories from that youth career, getting to train with great players in the first team and amazing managers.
"There have been good times and it's made me into the person I am now so I'm very grateful for all the amazing staff and coaches I've had and I'm pretty lucky to be where I am now playing football as a job."
