the world cup was probably the most deciding factor if you ask me, the wages a nice bonus.
Maybe he thought he could preform for a year here then move on to one of the title challengers after a successful world cup, I seem to recall rumours of a release clause at the time
We were just a means to an end for him. He was only ever interested in playing for England and Sven made it clear he would only be selected if he was playing/starting regularly. We were his only option at the time.
