TEAMtalk understands Crystal Palace and Reading have joined the hunt for Livingston starlet Matthew Knox.
Nottingham Forest had been leading the charge for 17-year-old striker, who trained with Manchester United last season.
He has already made his league debut and former Rangers chief Mark Warburton, now in charge at Forest, was hoping to get a deal tied up.
But now interest has come from elsewhere in England with Palace and Reading both ready to make offers.
Cardiff City and Leeds United are also believed to have asked Livingston to be kept informed of his situation with Sky Sports reporting that Cardiff will take Knox and team-mate Danny Mullen on trial next week.
Chelsea, Everton, Liverpool and Tottenham were reportedly interested in the young forward last season, while United are still tracking his progress despite deciding not to add him to their academy in the winter.
Livingston rate the youngster highly and boss David Hopkin claimed in January Knox was “something special”.
“He’s a young boy who has got great potential. I’ve worked as a youth coach for the past few years and five or six of the first-teamers at Morton came through the youth set-up when I was there,” he said.
“I know how good they are and rate them but Knox has something special and something different,” said Hopkin.
Livingston rejected a £75,000 offer for Knox from Rangers last summer and reports suggested United would have had to pay £150,000 for the player had they decided to sign him in January.
