England boss Fabio Capello has warned his players they must step up their performances.

England won their two summer games against United States and Trinidad & Tobago after missing out on Euro 2008.

But Capello, who is planning for the World Cup qualifying campaign that starts in September, has warned his players that they will have to start raising their game at international level.

He said: "With respect to our last two games, we must start again and show improvements.

"I expect my players to continue doing what I ask them to do."
