Manchester United have again invited Livingston youngster Matthew Knox on trial.

The 17-year-old striker has already trialled twice with the Red Devils but is set to return to Carrington for another training stint with the famous club, according to the East Lothian Courier.

Knox has previously visited Liverpool, Everton, Tottenham Hotspur and Nottingham Forest and is also a key target for Scottish Premiership giants Rangers.

It is understood that United could bid £150,000 for Knox who has featured 15 times for the Scottish League One club.

And Sir Alex Ferguson is expected to be used in a bid to persuade the talented Scotsman to make his way across the border to link up with Jose Mourinho's club.
