Ling lays down the law with cup heroes Orient
Leyton Orient players will be hit in the pocket if they mention the word 'Charlton' before the teams' FA Cup fourth-round clash at the end of this month.
After their remarkable 2-1 win at Fulham in Sunday's third-round tie, the Os have landed another London derby against Premiership opposition.
But manager Martin Ling has warned his players each utterance of the south-east Londoners' name will cost them £10.
'I will give them until the end of tomorrow's training session to talk about Charlton, and after that it will be banned,' Ling told PA Sport.
'Maybe everyone will have to shout `Charlton' 10 times at the end of the session. But (defender) Matt Lockwood is in charge of the fines, and I'm expecting to have to cough up a couple of times myself.
'It will only cost them a tenner each and it will all go into the players' pool, but we did a similar thing before the Fulham game - and we took nine points from a possible 12 over Christmas and new year.
'It is a great draw for us. Chelsea would have been the ultimate dream - but Charlton is fantastic too. It's another London derby and it's a club we have close links with because it's only seven miles away.'
Two successive matches at Premiership grounds should allow Ling - whose team are fourth in Coca-Cola League Two but only two points behind leaders Wycombe - to bring in the centre-forward and centre-back he covets.
But he is putting the brakes on those who believe the cup ties will land Orient a transfer kitty of more than £100,000.
'I have not paid a transfer fee for 28 months, and this will allow me to pay out a couple of small transfer fees as well as wages,' he said.
'But those who talk about six-figure sums are exaggerating.'
