Well, by referencing the money spent, the implication is that it cheapens the achievement. 'Well sure you won promotion, but you spent loads of money' Do you see? When the world and his dog is adding a caveat to your achievement it ruffles feathers. Had people said 'Well sure, you won promotion, but Hughton had the most time to work with the best squad', I'm sure you'd feel the need to defend his achievement, no?
I would say, I'm damn glad we've got Hughton as our manager, and that we have kept him. We're happy with the stability we have at the club and the way we're building. Rejoicing, not defending.
If I were a Newcastle fan, I would say I'm damn glad we had £55M to spare, and that Benitez spent it well. Rejoicing, not defending.
