Defensively Shaw has been excellent. Wan Bissaka is not ‘so much better’, and in what way is he currently better in fitness?
Shaw has quite rightly just won player of the year. To buy in his position this summer would be daft, as there are at least six other spots to upgrade before left back and we aren’t going to be signing anywhere close to an entire new team.
Having two very competent defenders at full back really wouldn’t be horrible, just as bringing in an athletic destroyer in the holding midfield position wouldn’t hurt. Sure, it’s not going to transform our attacking play, but it might at least stabilise the team and make sides work harder to score against us.
If we really wanted to go with a nice balance of one attacking, and one conservative, full back then we should look to bring in a right back who bombs forward. Or just properly play Dalot.
