LONDON, Jan 24 - Charlton Athletic striker Jimmy Floyd Hasselbaink has been fined 5,000 pounds ($9,866) and warned about his future conduct after saying his former club Chelsea had paid illegal bonuses, the FA said on Wednesday.

The Dutch striker was charged with improper conduct and/or bringing the game into disrepute after writing in his autobiography that Chelsea had paid an extra bonus to players after beating Arsenal in the quarter-finals of the Champions League in April 2004.

The Premier League investigated but found no evidence for the allegations.

"Such a payment would have breached Premier League rules," the FA said in a statement.
