One man's "bottle job" is another man's "loyal servant".
Personally, I'm surprised there aren't more 'one-club' men in football. By committing to the Saints for his whole career true legend status is bestowed for all eternity.
Would Steve Bull have been as much of a football legend as his is now had he left Wolves to join, say, Aston Villa? (and, yes, I'm aware that he played 10 matches out of 485 for two other clubs).
