Millwall Football Club are threatening to report Portsmouth FC to the Football Assocation if they continue to show an interest in youngsters Tom Kilbey and Sam Walker.
The Premiership club have already been warned by The Lions about their behaviour in relation to the pair and the club turned down an offer from Harry Redknapp earlier this week.
Midfielder Kilbey, who made his senior debut against Swansea City on Tuesday night, and goalkeeper Walker are both highly-rated within the game and the club are worried that they may be poached in similar circumstances to David Amoo, who left The Den back in July to join Liverpool.
