England coach Fabio Capello felt that his team's 4-3-3 system was a key factor in his team's 2-0 win in Wales.
Frank Lampard and Darren Bent scored as England moved to the top of Euro 2012 qualifying Group G.
"We played really well, we passed the ball quickly and created chances to score goals with no chances for Wales," said Capello.
"This formation is really good because some players like Ashley Young are improving a lot."

Bent spearheaded the front line, with Wayne Rooney starting on the left and man of the match Young on the right.
"The goals that we scored were really nice and in every moment we were focused on the game, which was important," added Capello, who hinted that he might make 11 changes for the friendly against Ghana at Wembley on Tuesday.
"I decided after watching games Wales have played to use Parker and two midfielders. I decided for a new position for Rooney and Young.
"When we are defending they stay wide, when we have the ball Wayne comes in and it was a problem for Wales.
"Parker is a good player in the holding position, he won back a lot of balls and we need someone like him in that role."
Lampard put England ahead from the penalty spot after seven minutes following a clumsy challenge on Young by Aston Villa team-mate James Collins.
Bent then slotted home a low cross from Young after 14 minutes as England built up an impressive early lead.
"It was a new formation for us but people knew what they were doing and it worked," said Young.
"We worked on getting the ball back as soon as we lost it and putting them under pressure straight away."England captain John Terry
The match was the first since John Terry was reinstated as captain of England on a permanent basis - and the central defender was pleased with a winning return to the role.
"The new system was very positive," said Terry. "The attitude was to get at them and press them high up the pitch to stop them breaking out early."
The vast majority of the 68,959 supporters inside the Millennium Stadium booed throughout God Save the Queen as the national anthem of the England team was played prior to the match.
"It was not nice and sometimes it can have the reverse effect," added Terry when asked if it motivated his players.
"We set the tempo early and it was very important that we over-powered their fans, we silenced them after the opening goal."
Terry revealed that England had practised regaining possession in the build-up to the game.
"We worked on it and during the first half we did it really well," added Terry. "In the second half the lads felt a little bit tired. We are back on top of Group G and we must keep winning."
Meanwhile the Football Association will not be making a formal complaint over the shining of lasers in the eyes of players when Scott Parker was replaced by Phil Jagielka.
