Manchester United will take a third look at Scottish teenager Matthew Knox as they ponder a £150,000 transfer.
The 17-year-old forward broke onto the scene for Livingston when he made his first team debut just over a year ago on Boxing Day 2015 against St Mirren.
He has had trials with Tottenham, Everton, Liverpool, Norwich City and Rangers, scoring at each club in training games.
Rangers had a £75,000 offer rejected for him in the summer and Livingston hope United will cement their interest with a bid this month should Knox impress again this week.
