"The interest has been there for some time, he said after completing the transfer.
"I'm thrilled to get this over the line. "The fans were a deciding factor for me. I know I'm going to play really good football here. To have the backing from the fans straight away is amazing.”
Boss Neil Harris is pleased to have brought in Moore saying
"I'm delighted to finally get him here. It is no secret that we tracked him in January but it wasn't possible at the time. Obviously he came here and scored two goals a few weeks later.
"He's a quality striker at this level. Our fans are fully aware of his ability - after that game and his appearances in the Welsh shirt.
"We're very pleased to get him on board."
