Former England boss Sam Allardyce has urged Gareth Southgate to drop his 3-5-2 system for Saturday's quarterfinal against Sweden.

The Three Lions defeated Colombia last night on penalties, and Allardyce thinks they'd be better served having another attacker against the Swedes.

"It was nail-biting indeed," Allardyce told talkSPORT.

"But if I was in Gareth's shoes, and I know I'm not, I would seriously consider changing the system.

"Defensively we look extremely sound, but I think we need more attacking prowess going forward to try and score more goals from open play.

"I don't think they need to play with three at the back against Sweden. They could cope comfortably with two defenders, I don't think they've got anything to concern us going forward.

"I would put the extra man in midfield or put three at the top. I think that might work. Stick Rashford in.

"England have not scored enough goals from open play – even against Panama it was one great goal from Jesse Lingard and one deflected shot off Harry's heel."
