Rangers boss Mark Warburton has revealed that they are on the verge of signing winger Harry Forrester from Doncaster Rovers.

Forrester is undergoing a medical today in Glasgow ahead of joining the Scottish Championship side when the January transfer window opens on Saturday.

Warburton has previously worked with the 24-year-old at Watford and Brentford and believes that he can bring quality to Rangers.

"I know Harry very well, I know him from Watford. We are working with Doncaster, who are being tremendous with us in that respect," Warburton told Sky Sports News.

"Harry is in having a medical today and we will see how that one progresses.

"He has the quality on the pitch, that is very evident. Off the pitch he's a good lad and gets on well with the boys in the dressing room. He will add some quality to our squad."

Forrester is free to leave Donny having not featured for the League One side in over two months.
