CB – Cesar Azpilicueta
The club captain is likely to play most of his games as a centre-half in the opening weeks of the season, although his position could come under threat if Wesley Fofana arrives from Leicester.
Azpilicueta will need to use all of his experience to ensure that Son doesn’t cause havoc on Chelsea’s right flank. James may have to tuck in and help his older teammate out with the South Korean.
