It's obviously my untrained eye but the Serie A champions being in at that price makes no sense to me.
Like, a mid-table Premier League team - obviously he is English, he fills one of those pesky homegrown spots, he has played quite a bit of Premier League football now (some of it badly), left footed, if I squint a bit then I can see it, obviously all the European money is in this league too.
Serie A - he doesn't speak Italian, who knows how he'll settle, no HG quota in play and how could you watch his last season and think "yes, that is the man for us". Napoli don't even play the back three where he has played all his best football. And you're in the Champions League! I can categorically say he is not a Champions League defender.
But they're welcome to bid.
