Real Madrid legend Iker Casillas aimed a majour dig at Jose Mourinho after Manchester United’s defeat to Liverpool.
The Spaniard fell out with Mourinho during his second season at the Bernabeu and was dropped in favour of Antonio Adan and Diego Lopez.
After all Casillas moved to Porto and then Chelsea but he never forgave the United boss for destroying his relationship with Supporters.
"According to a Portuguese newspaper someone said that a player like me (37 years) is at the end of his career. Completely agree," tweeted Casillas.
"My question is, for that newspaper: in the case of coaches, when and at what point do you see that they are no longer to lead a team or train?"
United face Cardiff next Saturday before hosting Huddersfield on Boxing Day.
