We've tried him there once or twice in an emergency when chasing and it wasn't great. I also felt like he hated it. I said this is the game thread, but I'd play Musa there when Caldara comes back. We are essentially playing 3 at the back when attacking, so might as well do that.
I think replacing Suso with another midfielder and just playing a 4141, would be best. He slows down every attack, he sends in aimless crosses and is predictable, he loses the ball constantly, and can't hold onto it when we need him to.
I'd love to bring Bakayoko back, let him and Kessie destroy everything, put Bennacer in front of them, then Hakan and Paqueta as two free roaming attacking mids to create chaos with Theo bombing up the left to join up with Leao.
I hope if Piatek can get form, then a 4312 would be our future. Playing Leao and Piatek together with Hakan behind them. Hakan looks so much better further forward.
