Speaking to the official site Collins said: “I’m obviously delighted to sign, as it was worrying me a bit that I’d have to leave again!
“To be signing for another two years, I can’t explain how happy I am to be part of a Club that is moving forward and getting bigger and bigger, so to be part of that is unbelievable.
“I try to be professional, as I’ve been in teams where players make a negative effect when they’re not playing, so I am just proud to be part of such an amazing Club. I’m happy coming in every morning, whether I’m playing or not playing, and I train hard and try to keep myself fit.
“Like I said, to be part of such a big club for such a long time, I’m a very lucky boy. To sign for another two years is something that, to be honest, looked doubtful at the start of the season, so I got my head down and trained hard and tried to show what I could do.”
