Cork was a youth player at Stamford Bridge, before joining the Saints permanently in the summer of 2011, and admits the uncertainty at the very top of the club makes it hard for young players to make an impact with the west London side.
"Chelsea was massive for me and from eight years of age it was my dream to play for them," he added.
