One of the most noticeable features of England's play against Moldova was that it succeeded when it was simple. Every time someone tried an unnecessary back heel, a clever headed pass back to the goalkeeper or a piece of overly complicated footwork, things went wrong.
Attacks were broken up when easy options were ignored in an attempt to go for glory; Glen Johnson provided Moldova with their best chance of the night with his headed cross. Alex Oxlade-Chamberlain got into trouble when he attempted to use clever footwork instead of merely putting the ball past a defender and chasing the ball down.
Whilst none of this caused England any real harm against Moldova, Ukraine has the players to take advantage of these errors and Roy Hodgson must do his utmost to prevent those mistakes occurring.
The English national side is not blessed with the technical genius of the likes of Brazil, so it makes sense to play simple passes, build pressure and look for openings.
It was noticeable that England's second and third goals were created by simple, but high quality passes. There was nothing overly intricate about them, but that does not make them any less effective.
Ukraine will, obviously, defend better, but England still have the players to exploit gaps and score goals without flicks and tricks that are likely to waste possession and catch England out of position.
