is it your water or wiki saying 12.5% ? I quoted this a couple of days ago after reading wiki and said i hope it is on profit and not total fee.Andersen was acquired from Lyon for a fee of up to £17 Mill. I have a 'Feeling in my water' that there was a 12.5% sell-on clause.
If Fulham are prepared to offer him a 25% pay rise (he was already on great money at Palace) and a 5 year contract good luck to them.
He has been a great servant to the club and his partnership with MG has been top draw. I wish him well
