Maddison opener KO

JAMES MADDISON will miss England’s World Cup opener against Iran today.

The Leicester attacker (above) has been struggling with a knee injury and hasn’t trained with the team since Wednesday.

Kyle Walker is training but remains a doubt for the Group B clash with a groin injury that has kept him out since September.

Otherwise Gareth Southgate has a fully-fit squad to pick from.

The England boss is expected to play a back four today, with under-fire Harry Maguire set to start.

Raheem Sterling has warned England over complacency against Iran.

The Chelsea ace told the Lions’ Den: “The outside world, or the people at home I should say, think it is a game we should win but I think it’s complacency.

“These are the teams that can surprise you and we don’t want to get surprises here.”
