The 16-year-old precocious striker reportedly snubbed Manchester United on January transfer deadline day this week, Allsoccerplanet understands.
Matthew Knox, who had trial at United for a week in January, impressed coaches at Carrington with his skills in front of goal. He even reportedly scored a stunner past veteran goalkeeper Victor Valdes in training as United looked to bring in another striker on a permanent basis.
United were keen to offer Knox an offer to stay at Old Trafford, but the teenager opted to remain with the Scottish club instead.
“Man United came back in for him yesterday (Monday) and there was interest from QPR but Livi are holding on to him,”said Knox.
“It’s a good felling knowing that these clubs want him.”
Knox became the Scottish Premier League’s youngest ever player in on Boxing Day when he came on as a substitute.
However, the Livingston FC striker has now emerged as a shock summer transfer target for Arsenal who are desperate to revamp their ailing youth system.
He has also been on the radar of both Chelsea and Liverpool in the past.
