Im more thinking about our transfer business / budget for this window.
If we are to try and sign Partey, then we would have to pay the full release clause up front apparently, & that likely will take most of our budget. I think it's part of the reason we are in for Willian & will likely try for Coutinho on loan.
Think to buy anyone else we'd need to rely on sales, so you're talking about what we can get in for the likes of Guendouzi, Sokratis, perhaps Holding etc, that's why I doubt we would spend much over £30M for a defender.
