Don't worry. Our owners and transfer committee have mapped out a plan to replace him by 2032. Finding the "right" central defender takes time, you know.100% this. He's still our best defender but he's no longer infallible and increasingly passive.
If we're not trying to recruit his successor in the next two windows, I don't know what we're doing other than not learning lessons.
And if someone were to knock our doors off with a huge offer, we should be strongly considering it.
