The way I look at it this. Wan-Bissaka is the best in Europe defending 1v1 on the ground. He's more than decent in several other areas too but being a master at 1v1 defending on the ground makes him worth every penny. With Maguire it's similar, only Maguire is one of the very best in the air, that's his main strength. He's also more than decent in several other areas, including "on the ball", something everyone seems obsessed about nowadays. He's not left footed but he can play LCB, something that not all of our CBs are able to do. I cannot find ANY quality left footed CBs. Our squad of CBs would improve with Maguire, so he's worth buying. Even if we pay £20 million more than we'd like to.
