He told the club website: "Mark is a midfielder I've had an eye on for a while.

"He's a talented player, a good user of the ball and I think he will just add quality to the squad.
"I'm looking at him just to help us over the line for the rest of the season and then who knows? Maybe depending on how it goes he may be someone I look at for the future."
