Colorado Rapids forward Brian Mullan admits his mid-season move from Houston Dynamo has been a very good one.

The 32-year old has been a key part of the Rapids side that has qualified for the Eastern Conference final, where they will meet San Jose Earthquakes, and he has thanked the club's assistant coach for teaching some tricks of the trade.

Former Leicester City and Celtic wideman, Steve Guppy, works closely with the Colorado midfielders and he has been a great help according to Mullan.

"I've been working on a lot of one-on-ones, which I feel like that part of my game got a little lost in Houston," Mullan told soccer365.com.

"Working on them every day is giving me a little more confidence so hopefully it will keep coming."
