Jorginho was benched for a significant part of the season because Diawara outperformed him, he's a pretty decent player mind you but it won't be long before he permanently loses his place in their starting XI.
Sarri didn't know how to get them playing together, but that doesn't mean Jorginho isn't as good as Diawara or that Diawara outperformed him, he just chose the more physical player and it was a mistake IMO.
In fact once Sarri brought Jorginho back in the started playing much better and finished the season incredibly.
Jorginho is the definition of a Pep player, constatnly open to the ball, always knows where it's going to go before he's already got it, positionally brilliant. I'd love him here, and if Sarri doesn't rate him as high as Diawara (who don't get me wrong is also great), we might get a better fee.
