Rangers are confident they can sign Livingston striker sensation Matthew Knox, according to manager Mark Warburton.

The 16-year-old had a trial at Manchester United during the January window after previously undergoing trials at Liverpool, Tottenham and Everton.

Scottish Championship club Livingston rejected a bid from Nottingham Forest and also fielded enquiries from United and Queens Park Rangers.

Knox is currently undergoing a trial at Rangers and Warburton believes an open pathway to the first team gives the Scottish giants a crack at landing the teenager.

Outlining Rangers’ bid for the youngster, Warburton told a media conference: “Knox is a smart, talented boy. He’s confident, good in possession and technically gifted.

“I believe you have to show there is a pathway. If there is a glass-ceiling there, you have no chance. If you are telling an Academy player to eat well, sleep well, train well, play hard and be the best they can be but there’s no chance of making the first team, that can’t happen.

“You hear that Man United or Liverpool or Chelsea or Arsenal, are keen but their web is so far reaching and deep that a number of players are being watched. But to sign for those clubs and then play is a different proposition.

“Too many times, you see clubs blood someone and then you never see them again. It’s like another box is being ticked. If he’s good enough, you make sure there is an opportunity.”

Knox caught the eye of the United coaches with a goal past former keeper Victor Valdes in one practice match.

Manchester City and Chelsea are also tracking the the player’s progress and his manager at Livingston, former Scotland international David Hopkin, is convinced Knox can reach the top.
