Would not be remotely surprised if he featured in the shield and was on the bench for chelsea. Including him portrays a willingness to reintegrate him even if its not the reality and stops Barca who have taken the piss knowing we have no bargaining power from taking the piss even further. Sends a message to them to put in a respectable offer or fuck right off.
I don't expect this at all but in the extremely unlikely event he's still here after the window closes, if Pep shows a willingness to give him another shot I wouldn't be unhappy. He's a quality player and having adept cover in both fullback positions is needed.
