He'll actually get playing time unlike at Barca. He started at Lyon so it'd make sense he might want to go back there
I realise that, but they've fallen quite a bit behind PSG because of the money. More of sideways move tbh.
Lyon is definitely a step up from Nice to be fair.
They are, but he'll still be playing for a team that can only really finish second or third in their own league because of the power PSG have. He's better off moving to none of the 3 mentioned tbh as IanPardewLover says.
