Btw, when I said sacrifice him, I didn't mean sell him and then get all confused a la Tootsie. We need a plan. Our midfield is ass, lots of weak players, both physically and mentally, and there are some ageing elements.
If it were up to me, and we would get decent coin, I'd sell every single midfielder we have, with the exception of Bentancur.
If we could somehow bring in both Pogba and Tonali, and Pjanic is the sacrificial lamb, so be it. I'm definitely not in favor of selling him if we're not going to significantly upgrade the midfield. We've sold Vidal and Pogba, both far superior players, in the past. I'm sure we can survive if we sell a 30 year old Pjanic.
