Manchester City fullback Kyle Walker says England's players must buy into coach Gareth Southgate's approach.

Walker insists they now have a new mentality going into the World Cup.

“I feel if we can just control the game a lot better, which we are working on in training, we will have a good tournament.

“People say we aren't streetwise compared to other countries, but that's us as English people. We are very honest. We will run for 90-odd minutes and sometimes you need to say, 'OK, let's pull the reins back a bit, let's control the game with our ­passing and keep the ball'.

“When we have the ball, ­opponents will have to run. The likes of Spain and Germany ­believe in a certain ­philosophy. We need to take that into a tournament and ­believe in what we are trying to do and what we are trying to achieve.

“If the crowd are getting on us and booing us, don't worry about it. We must believe in us, as a set of ­players, believe in the manager and believe in what we are trying to do and achieve."
