I 99% agree with you but selling Rodri would be a pretty damning thing to do.
For a start, they had years to get this transfer right. They decided FDJ was too much, they decided not to play games with Jorginho, then they had an entire year to pinpoint the guy they needed and settled on Rodri, who it's worth remembering was valued much higher than €70m by Atletico Madrid, who had given him that buyout clause before he arrived at the club when he was still breaking through at Villarreal - they wanted it to be double that, and Rodri was regarded as the best defensive midfielder in Spain.
So now by replacing him they would be admitting that they picked the wrong guy. Not a guy who isn't good enough, but one who didn't suit the system, which is really bad.
However, this guy who's being shipped off in the summer is still undroppable in 2020/2021. So what does that say about Fernandinho? or Gundogan? or even Tommy Doyle? They're all worse than the guy who's so bad he's getting hooked.
