Race for the World Cup

Is it me or does this happen every time we encroach on a World Cup?
Wednesday night Theo 'fish out of water' Walcott put in an England performance that was full of energy and pace but devoid of any quality when he received the ball. Wright-Phillips came off the bench and looked useful pocketing a goal in a decent of the bench performance. Beckham sat on the bench not even needing to kick a ball to remain a favourite for the finals in South Africa.
Then we get to Saturday. Arsenal v Burnley and all of a sudden Walcott looks the business; scurrying runs delivering dangerous balls into the box and scoring a sublime goal which put him back in the forefront of Fabio Capellos thoughts. Its infuriating but I guess that's football. It's a nice problem to have for England.
On the other hand there are other players like Peter Crouch who can not do hardly anything of purpose for their club (ask Liverpool fans as well as those at White Hart Lane) but somehow get selected for the national team and if you blinked you will have missed it but he now has 20 goals for England. Hands up if you saw that coming five years ago? Thought not. It's a funny old game....
