If we ended up with De Jong and Phillips, we've pretty much covered off Bernardo's skillset. If you need non-stop running and tenacious tackling and pressing, pick Phillips. If you want to hog the ball and have deep lying creativity, go for De Jong.
Obviously you're not getting it in one player, but both also have their areas where they'd add more to the team.
Rodri, Phillips, De Jong, KDB, Gundogan is a fantastic selection of midfielders that lets you build any kind of midfield you want, for any formation or tactic.
I'd sooner end it with Bernardo but as I said earlier, I'm fed up of his constant pining for a club with worse prospects, in financial turmoil, a board who treat their current players like shit and a fanbase that won't award him the cult hero status he's claimed here. If he doesn't want to be here he can go. If he does, shut the rumours down and get on with it.
