United Gaffer, Dave Frecklington wanted to add a play-maker to his options and with Karl Cunningham only a loan player O'Halloran certainly fits the bill.
A creative player with an eye for a goal he will add something to United's improving squad.
He has 14 goals in 49 appearances for the Whites and never played up-front. Add that to his assists and you can see what Freck is looking for.
Matt began his career with Derby County and Chesterfield and spent several seasons at Kings Lynn.
He is only 30 and has a good few years under his belt yet.
