Graeme Souness has slammed Casemiro and Raphael Varane, claiming Man United have been taken for a ride by Real Madrid by selling the two to them.
"Yeah he [Casemiro] can point to the medals which he won but he was a bit-player in a very special team.
"I never saw him coming to United and being the difference. I saw him as 'he's okay, not a big player'.
"I think they've had their trousers taken with both Raphael Varane and him. If you've got something to offer Real Madrid don't sell you.
"Real Madrid sold Raphael Varane and Casemiro to Man United. They [United] paid a premium and I'm sure they're on lots of money those two and it's a football decision, that I feel, they got wrong again."
Souness added: "He's [Casemiro] been found out, not stitched up. If you're a big player and you've got the chance to go United, you're going to take it to make them better."
