Every season, King has at least one bad game where we proclaim that its the end of the King, that he should retire at the end of the season etc etc. Only for him to then come back next game, dominate the other team and we all announce he's amazing again.
Let's be clear, King has gone downhill. Clearly. He's much much slower and much less mobile than he was before. His brain is still as quick as ever but sometimes his body just doesn't quite obey. So he's worse than he has been in previous seasons. And every once in a while, especially when the midfield becomes non-existent, he gets exposed by waves of attacks and comes up looking a bit silly. And for all the mocking of Arsenal throughout the season, their front 6 is still one of the best, fastest and most technically accomplished in the league, especially when on form.
But he's still an excellent defender. Even now, with no knees and no training. His effect on our win percentage isn't a coincidence. The effect of his presence on the team isn't a coincidence. He's played a huge part of us sitting in 3rd right now. King stays at the club until he decides its enough imo. Or if we get to a point where King is having a very clear detrimental effect.
But still, in the long term, I'd like us to build a reliable, consistent back two and that means we have to try to buy so that King is no longer an automatic starter when fit. Harder said that done though.
