When Jose Mourinho leaves a team, they normally struggle to cope with the effects of having The Special One move on.
Porto and Inter Milan - teams the Portuguese manager led to the Champions League trophy in 2004 and 2010 - are two examples. Both are already out of this season's competition, and in Inter's case, the team are even struggling domestically.
And everybody is aware of Chelsea's problems. The Blues are also struggling in Europe and in the Premier League.
The problem with these teams is that they failed to freshen up teams that Mourinho built, thinking that the same players he once acheived success with, could do the same under any other manager.
