“We’ve bought Murray with the help of our supporters’ club, the United Club, without whose help we couldn’t have done it,” Christie said.
“It just shows you how good they are as they have helped with the transfer fee.
“It’s incredible. I’m lucky to be the manager of a club with supporters giving you that backing.
“Murray is athletic, he’s six foot two stroke three, he’s good in both boxes, he’s no stranger to the ball, he’s calm and he’s got a wee bit of an edge to him.
“ Hunts (Stuart Hunter) can’t go on forever. We’ve got Jamie McCormack suspended so we just felt that Murray is a player who’s become available who’s played at a good level.”
Bo’ness, not in competitive action last weekend, are 13th in the Scottish Lowland Football League with 20 points from 15 games ahead of this Saturday’s home league game against Rangers B.
“We’re looking forward to it,” Christie said. “It’s a great fixture for us playing a Rangers XI at home.
“It shows the level we’re at now. These are the games that you look forward to.
“The last time we played them it was 0-0 with 10 minutes to go and then they scored two late on.
“It was the same when we played Celtic as well, so we are not far away.
"Rangers Colts have been beaten as well. Gala, Civil and Cumbernauld Colts have beaten them, so we can beat them.”
Bo’ness also have an away league game against Broomhill next Wednesday night.
Christie said: "We had a lot of new players in at the start of the season and for whatever reason, natural selection at any football club kicks in.
“We feel that we now have a good squad together that can win football matches.
"I think we need to go on a winning run. We played Stenhousemuir in a friendly last Thursday and were 2-0 up and drew 2-2, after losing by the odd goal to Edinburgh City in the cup.
"So we’re trying to get them to compete, go up a level and we’re working hard on that.”
