Nottingham Forest have reported Tottenham Hotspur to the Premier League for making an illegal approach to Morgan Gibbs-White – and have threatened to sue their rivals.
Incensed Forest officials claim Spurs tapped up the player – against the rules – ahead of what is set to be a £60m move.
The 25-year-old has a release clause which Spurs are thought to have triggered, but Forest are furious with their approach and have accused them of effectively tapping up the player.
Mail Sport understands Forest have now told Tottenham not to make any further contact with Gibbs-White and have written to both Spurs and the Premier League.
