England star Mason Mount has admitted that rest and recovery are the keys to World Cup success.

The Three Lions begin their tournament against Iran on Monday, hoping to qualify from a group that also contains USA and Wales.

Mount, who has been playing a lot of football for club and country in the past two years, admits staying in top condition is so important for him.

"Yeah, they're quite relaxed," the Chelsea ace said about the atmosphere in the camp, per the Daily Express.

"I think this tournament, it's three days or two to three days before the next game.

"So the most important thing is about recovery, about rest, and trying to feel 100% going into each game because these games come thick and fast and we're playing a lot of games at the moment for our clubs.

"That sort of downtime is important to kind of rest and recover."
