I'm playing with Lille and I need a replacement for Adil Rami at the end of the season, because he is only on loan from Valencia. I will probably be able to spend 5-10 mio.
Otamendi would be great but is also quite expensive. Try Kana-Byik from Stade Rennais, he develops into quality if played regularly. But if you can, get Toby Alderweild, he is quality!
