"It wasn't about money or anything else really, just a desire to challenge myself again," Gordon tells The Scotsman. I made up my mind that I was leaving by the middle of the Six Nations and I spoke with Hugh Campbell at Glasgow about it so didn't get into talking about money or contracts.
"It was a hard decision but I have been at Glasgow for ten years and felt I'd become a bit stale, and that was maybe reflected in some of my performances this season. I wasn't happy with that and knew something had to change.
"But the facilities in Scottish rugby are poor and what has been particularly disappointing has been the fact we haven't improved them over the last ten years. At Glasgow we've moved about from Dalziel to Scotstoun to Whitecraigs and Hughenden, and still we don't have anywhere the players feel at home. We have better weights facilities this year but we still don't have a good indoor facility, which is vital in British weather, and nor do we have decent training facilities.
"I wouldn't say it was a crisis, but I know it is something that the players at Glasgow find very disappointing and I feel it is something the SRU has to look at very seriously."
"The players at Leeds undoubtedly have a greater chance of performing well regularly, and reaching higher standards, when they have the support around them that they do."
"Apart from the facilities at Headingley, geography was a big consideration," Gordon said in today's Herald. "My wife, Jenni, has a good job in Scotland and the aim is for her to work a four-day week and be with me the rest of the time."
