Three Premier League titles, one FA Cup and three League Cups - Jose Mourinho is arguably Chelsea's best ever manager.
The Portuguese boss has played a key role in transforming the west Londoners over two spells totalling five years.
The 53-year-old will be returning to Stamford Bridge with Manchester United on Sunday, for the first time since his dismissal in December, which came after the Blues' dreadful title defence.
Fans backed Mourinho up to his final days in the hot seat, but some feel he damaged the club on his second spell and will not want to give a rival boss a warm welcome.
