Murray put pen to paper this week and immediately spoke of the reasons behind his move to the Midlands in a bid to help the club's league and cup campaign.
He said: "I looked at the ambition at Warriors and it's important to go somewhere where the set-up is right and everything is geared in the right direction - to bring success to the club.
"It's always been a difficult place to go as a player, so it will be nice to have the fans right behind me and it will definitely be a more enjoyable experience. I'm looking forward to getting out in front of the fans and showing what I can do.
"There is a big fan base and great facilities. The support the Warriors have had has always impressed me and it would be good to give the fans what they all want."
