Chelsea legend Ron 'Chopper' Harris is excited by the return of Jose Mourinho.
Harris is in no doubt Mourinho can push the club back into contention for a first Premier League title since 2010.
"If you have a look at every club Jose has been to, he has always been successful," Harris told Press Association Sport.
"People will say he has not done that well at Real Madrid, but he took an unfashionable club like Porto to winning the Champions League, and did the same thing at Inter Milan.
"If he was to come back to Chelsea again, and with one or two adjustments to the squad they will be a major force, challenging for all the major honours again next season.
"If you look defensively, they are quite sound, maybe they will be bringing in another full-back, then a midfield player and another striker or wide player, that would give Chelsea an awesome squad of players."
