Gonzalez recently hung up his whistle and the former Uefa referee has not wasted any time to voice his dismay with the Portuguese coach's behaviour.
"He has a lengthy history of criticising referees. Just look at how he behaved in England when he was at Chelsea, in Italy during his spell with Inter, or in Portugal with Porto," Gonzalez said to Ona FM.
"If you talk to the referees in England and Italy, you know how they all think about Mourinho. Just look at his behaviour there and you'll realise that what he's doing now is nothing new."
The 45-year-old Gonzalez officiated La Liga matches from 1995 until 2012, but retired earlier this year after a dispute with the Spanish football association.
