One world class CM, and one world class CB is all we need imo. Ramsey coming in, sign a youngish top class CM like Pogba, Saul, Ndombele... and sign an aggressive, top class young CB in the Chiellini mold, like De Ligt.
Sell Dybala or Costa to fund the moves if necessary, as one of them is surplus right now, unfortunately, and our team would be much better if we upgraded other departments even if it would suck to lose one of them.
