England international Gareth Barry believes the national team's midfield will improve further the more they play together.

After a convincing 4-0 win over Kazakhstan, led by the midfield of Frank Lampard, Steven Gerrard, Wayne Rooney and himself, Barry can only see more improvement from the foursome.

"The more we do play together, that midfield, the more we are going to get used to the role," Barry said.

"Steven and Wayne are mixing in and out, they are linking up well, and myself and Frank are working as a two in the middle, so the more we keep playing together the better.

"We know there are tougher games ahead but we are going to learn from each other."
