Derby County striker Kenny Miller insists he has no regrets leaving Celtic in August.

"It was my decision that I wanted to go," insisted Miller. "Okay, there were other things that were a part of that decision, but, ultimately, if I'd wanted to stay at Celtic I could have stayed.

"I knew I was giving up Champions League nights. I knew I was giving up winning the SPL again or the Scottish Cup or whatever. All that was going when I signed for Derby. But there are high points there as well. You are playing in the English Premier League and it has been a joy so far."
