John Terry could arguably fill a list of his own with the number of supersitions the former Chelsea captain observed during his career.
The centre-back accumulated so many rituals that it became a joke among his team-mates, who began to wind him up.
So what sort of superstitions did he have?
He didn't like to touch the ball in the dressing room, which led to interesting encounters with Eden Hazard and others who liked to get a feel for it before games.
He used to listen to the same CD in the car on the way to the game - American singer-songwriter Usher, apparently - and would park in the same spot.
He would tie tape around his socks three times and make sure to sit on the same seat on the team bus on the way to away games.
He wore the same 'lucky' shin pads for 10 years too before ditching them following a defeat to Barcelona.
The strangest, however, involves going to the toilet and it's one that the entire Chelsea team actually got involved in.
"In the Chelsea dressing room we have three urinals and me and Lamps (Frank Lampard) started weeing in one," Terry told The Sun in 2016.
“We won the game and, for me, that was it, the next week there was a queue of me, Frank and Ash.The next week there were four of us and the week after there were five.
“And even now, up until today, you have Cesar Azpilicueta and Cesc Fabregas, we are all there in one big queue.
“A few months ago the club secretary said to me: ‘we have had a few calls from the FA complaining because we have been going out late’ and I didn’t have the heart to tell him it was because we were all waiting to go for a wee.”
