Everton manager Sean Dyche has banned snoods and hats from the club's training sessions.
He has also ordered all players to wear shin pads when they are training.
Dyche is known for having set rules that players must follow, with another demand that his players must improve their fitness.
Dyche stated during a news conference to reporters: "This has been going round for years and it drives me mad. Unless I've been out of the game for too long, you're not allowed to wear hats when you play on a Saturday, you're not allowed to wear snoods when you play on a Saturday and you have to, by the rules, wear shin pads. It is not rocket science.
"Everyone makes the mythical story that it's hard lines from Sean Dyche. It is just common sense. You train how you play, how can you train how you play if you have 14 snoods on, 15 hats and leggings, no shin pads, white socks, it's not relevant. I told the players, 'these myths I'm going to bust them for you right now'.
"I explained to them. There is not a single player here where everything is not explained to them. I'd be surprised if any of them are in the dark on anything. I explain everything to them and the reason behind it."
