A year is a ridiculously long time to be making predictions - certainly I'd couldn't have predicted Stones would be this good 12 months ago - but I have a feeling Laporte might move in 2022, and Aké will end up being the third choice CB long term.
I just don't think we're going to keep 3 world class centre backs happy long term, and the Dias-Stones partnership works so perfectly, you can see they have a chemistry and match each others games perfectly in a way that Laporte just doesn't seem to have.
So if I was Aké's agent, I'd be telling him that we're unlikely to have all of those 3 ahead of him long term, be patient and make sure you're fully recovered from this injury, have a big second season.
Hopefully they all play well and play enough to stay happy and everyone stays together long term, but clubs like Real and Barca, the Italian big 3 will need starting quality CBs in the next few summer windows so someone is going to be thinking they could play every game somewhere else.
