Some of these posts fluctuate between thinking he was average and those saying he was the greatest ever. They remind me of Dryden's couplet:
"So over violent or so over civil
That every man with him was God or Devil."
Let's have a rational, dispassionate assessment.
He was not perfect or world-class, but he was technically highly gifted. If he was (or seemed) selfish, it was because he knew that if he passed to a colleague, they would almost invariably cock it up. He was very skilful at keeping his body between the ball and an opponent, and was almost impossible to dispossess. He scored some blinding goals - as well as the Southampton one, the goal v West Ham in the Cup was fabulous. He could score from free-kicks, especially from the inside-right position (as we used to call it).
However, he did not have the vision of David Silva (or didn't use it - see above). He didn't put in a shift, particularly away from home. He could be nullified by close marking - Danny Maddox of QPR rendered him invisible in the infamous Game at Maine Rd.
But, as someone has said, he didn't deserve Joe Royle's low opinion of him.
He could light up a game and we should be grateful for that.
