Manchester United striker Wayne Rooney admits England's second-half fade-outs are becoming an issue.

Rooney had England ahead of halftime of their World Cup qualifier against Montenegro, only to be pegged back in the second-half.

Rooney said: "In the second half they came at us and we didn't keep the ball well enough at times. It was a lesson for us in the second half and we need to learn how to see out these games better."
