Andre Villas-Boas signed the defender for the Blues in January 2012 and the 27-year-old won the Champions League at his new club and became a regular England international under Roy Hodgson, only to be ruled out of Euro 2012 through injury.

"Like anything in football, it was when results started going badly that some Bolton fans started turning a little bit on him [Megson] and some parts of the stadium didn't particularly like the style of play. That's the way football is," Cahill told The Independent, before discussing his reaction to the sackings of Villas-Boas and Di Matteo.
"[Villas-Boas] signed me and it was strange for me, I was left out for a few weeks at first," he recalled. "I don't think it was a case of not fancying me, he brought me in, so he must have seen something in me.
"Maybe he thought I needed to be bedded in but it wasn't long after that he got the sack. AVB looked into things in real, real depth, unbelievable depth sometimes, which is his style and has obviously brought him success. With Robbie [Di Matteo], who'd already been here as a coach, that eased off a little bit, and the sessions were similar. Robbie was good at communicating with the players, whether you were playing or not."
However, club owner Roman Abramovich fired Di Matteo and appointed Benitez in November and Cahill sees similar patterns emerging for the Spaniard with the Stamford Bridge crowd, though he feels that his new boss needs to be given more time.

"At this moment a faction of Chelsea fans aren't behind the manager but I think players have to keep working hard and the manager keeps working hard to get results. If that happens, I'm sure it will turn round," the centre-back argued.
"Everyone wants this club to do well and win games, so it's a matter of everyone pulling in the right direction. That would be great. As players we've just got to keep fully focused and do as well as we can.
"The new gaffer is into knowing exactly what's expected of you. Tactically he's very organised, which has been good and made us more stable and more organised and compact. He speaks to you a lot and everything is trying to improve your game or the positions you should be in or he'll ask you what would you do in a particular situation."
