The former Liverpool boss replaced Roberto Di Matteo as the Blues’ temporary head coach until the end of the season after the Italian was sacked following a string of disappointing results.
Mourinho, who won two Premier League titles in three seasons at Stamford Bridge, watched his Real Madrid side secure their place in the Champions League knockout phase courtesy of a 1-1 draw with Manchester City.
And the 49-year-old expressed his disappointment at Di Matteo’s sacking after the game but backed Benítez, despite their previously frosty relationship from their reigns at Chelsea and Liverpool.
“That’s football. I’m never happy when a manager is sacked – never – because that can happen to me and this is a feeling that no-one likes to have,” Mourinho told Sky Sports.
“At the same time, everyone knows I like Chelsea. I always support any Chelsea manager in the same way I supported Roberto [Di Matteo] and was wishing him to do well.
“It’s the same thing I will do for the next manager.”
