I love the nostalgia of threads like this.
Xabi was a tremendous player for us - he announced himself with the Spurs game which Molby himself described as one of the great passing displays he's witnessed. He certainly didn't have a "devastating shot off both feet". I think it would be a stretch to suggest he had a devastating shot off any feet. Yes, he did score some goals and a couple of them were rippers but he was by no means a devastating striker of the ball. One of the (very few) complaints in his first season was that he had to add some goals to his game.
He had wonderful first touch control and used the ball to beat players rather than footwork or dribbling. He also knew how to "attract" a foul when needed, was tremendously calm in tough situations and despite the austere exterior was extremely passionate. The embrace of Stevie after the Chelsea semi final is something that will remain with many of us for life.
Anyone who's had a child knows he made the right decision to be there and miss the game but he seemed to allow this to unsettle him and he was desperately average for a season and a half. He was slower than ever, failed to control simple passes, took wrong options and was out of position. His passing, perplexingly, never seemed to truly suffer other than not "seeing" the defence splitting options. I imagine his "screw you" message to Rafa after his last season was very satisfying - I've always wondered about the fact that our two greatest mid-fielders of the last 20 years had major fall outs with Benitez.
He was never a better passer than Gerrard but took the simpler option more often which aided our control approach to games. He lacked Stevie's dynamism, his goal scoring prowess and his ability to cover the turf but was far more disciplined which amplified the calm control he could exert from the back.
Certainly not as great as many on here would have you believe - he was never a danger of being the best player on the planet. However, the way he started and the way he finished was mesmerising and, with the help of nostalgia, covers any short comings. I quake to think how highly our captain with be rated 10 years after he's retired and nostalgia has taken hold of his memory as well.
