Gareth Southgate says England must learn from their mistakes before the World Cup despite being pleased with aspects of their 2-1 warm-up win against Nigeria.

Southgate named close to his strongest side at Wembley on Saturday evening, and first-half goals from recalled Gary Cahill and captain Harry Kane had them cruising against the Super Eagles come the break.

However, four changes and a tactical tweak from the visitors saw England undone and looking uncomfortable in the early throws of the second half, with Arsenal forward Alex Iwobi scoring Nigeria’s first ever goal against the Three Lions.

From there, England never really recovered their verve or control, despite only truly struggling for a few minutes, though Southgate has warned another three minutes like that could well see them eliminated come the summer.

"[I am] really pleased with the first half," Southgate said. "An excellent performance with the ball. Really good movement and interchanges between the front four."

“We overloaded midfield and whenever Raheem [Sterling] or Harry [Kane] came short, we made some fantastic runs in behind. There was a lot of unselfish one and two touch play.

“Our play from the back had good composure. It was as good a half as we've had.

“It would be easy to say we were complacent second half, that wasn't the case.

“We didn't come to terms with their change in formation, work out their midfield quickly enough, and they had a long passage of possession and they got in behind us.

“In general we can improve on what we did. That five or six minute spell we have to learn from because, in a tournament, that's enough to put you out.”

England have another chance to cut those spells out of their game when they face Costa Rica at Elland Road come Thursday, before travelling to their World Cup base in Repino on June 12.
