"Everybody likes to enter with the right foot, right? I'm no different," he laughed when quizzed by reporters.

England's Dele Alli is using the same shin guards he has worn since childhood when he plays in Russia, hoping they bring the good fortune that has long eluded the Three Lions at international tournaments.
"I've had the same shinpads since I was 11. They are battered (but) I am very superstitious," the Tottenham midfielder told Fifa.com.

"Sometimes my teammates ask me if I'm not right in the head," the Paris Saint-Germain midfielder said.
"Every player has a ritual before a match and I usually hold my bag in my locker and I throw on two or three sprays of perfume. It gives me a feeling of happiness."

Colombian keeper Rene Higuita's insistence on wearing blue underpants.
Sports psychologist Dan Abrahams said, "Logically, these kinds of rituals aren't linked to performance"
"However, if a player creates the perception that they are, then the action can become a hinge factor for how a player feels," told the specialist to AFP, who works with Premier League club Bournemouth.
