Teenage forward Matthew Knox is heading to Manchester United next week to undergo his third trial at the club, according to a report.

The East Lothian Courier claim Livingston attacker Knox, 17, will spend a week on trial at the Premier League giants as they weigh up a move.

It is said that the teenager, who has previously been on trial at Tottenham, Everton and Liverpool, will begin his United trial at their Carrington headquarters next Monday.

Knox became Livingston’s youngest ever player at 16 on Boxing Day last year and has made seven appearances for the Scottish third tier side this season.

The report states Rangers have had a number of bids for the striker rejected, although it is not stated how much it would cost to sign the player.

Manager Mark Warburton has admitted in the past that the Scottish giants were keen to win the race for the versatile young forward.

Knox signed a new two-and-a-half year contract extension with Livingston last week, but is now set for a third trip to United’s training complex.

The starlet has made just five appearances for the Livingston first team this season, the most recent in the 4-0 win over Stenhousemuir on December 13.

In other Rangers transfer news, Warburton has given this update on two potential January deals.
