That's definitely worth considering. But if you can look past Laporte arguably being too large for LB he's got better passing and crossing technique than Aké from what I've seen, and is better in progression.
I'll leave it there though as I don't want to get into a big long discussion and I never really intended to create a debate. Aké is definitely more mobile and it's clear that the club see him as a viable option there and not Laporte, so I'm satisfied.
And yes, looking like Gullit can only be a good thing. It worked for Zinchenko with De Bruyne!
