The Football Association has confirmed it will analyse Didier Drogba's comments regarding deliberate bookings before deciding whether to take action.
The Chelsea striker claims in his autobiography that former Blues boss Jose Mourinho discretely told him to pick up a yellow card in a game, in order to sit out a match of his choice through suspension.
Drogba was happy to follow the Portuguese tactician's orders, as it sometimes allowed him to secure an additional holiday during the arduous campaign.
However, his comments have not gone down well with The FA, who are keen to read the quotes in full when the book is released in July, before deciding if any offence has been committed.
"Mourinho calculated everything. He looked at the match programme and analysed the cards each of his lads had received," he stated in his autobiography, C'était Pas Gagné.
"He sometimes whispered to me: 'It would be good for you to get a yellow card today. You would miss such-and-such a match. I will give you four free days'.
"No problem. I used to do as he said.
"That allowed me to pay myself a little trip to Dubai. It was a modern way of treating work and the individual."
