Sunderland boss Gus Poyet is unimpressed with the spate of footballers' books betraying locker room secrets.
Former Sunderland boss Roy Keane released his controversial book last week.
"I am not a fan of people writing books - I hate (those) books," said the Uruguayan, who takes his 13th-placed Black Cats to Southampton.
"You can't say one day that 'what happens in the dressing room stays in the dressing room', then write a book. I don't like it.
"It doesn't matter who you are, who wrote it, how much money you got or whether you give it to charity - I don't care. I don't like the books. Although mine would make a good one!"
