Blinkered nonsense. Based purely on who he signed for.
Wonder how many important games he would have played in for Norwich following their relegation? Wonder how many medals he would have won? Wonder what his Bank Balance would be following a relegation wage cut and no winner bonuses? Wonder if he has improved being around top players and being managed by top coaches?
He made the correct move for him at that time. And still has plenty of time to move South if he wants in the knowledge that he is now financially secure for life.
