There is no love lost between the pair after Mourinho dropped Casillas during his time at the Bernabeu
Iker Casillas aimed a brutal dig at former boss Jose Mourinho amid Manchester United’s continuing struggles.
The pair endured a strained relationship during their time together at Real Madrid, with Mourinho famously dropping the club legend in favour of Keylor Navas.
Casillas, now at Porto, has publicly expressed his disdain for the Portuguese boss, claiming he created ‘great tension’ at the Bernabeu.
And Mourinho recently hit back at the goalkeeper’s comments, describing him as ‘someone at the end of his career’.
But he may live to rue those comments as Casillas took to his own personal Twitter account to reignite the feud.
Following United’s dismal 3-1 defeat to Liverpool, which left them languishing 19 points behind the league leaders, Casillas tweeted: “According to a Portuguese newspaper someone said that a player like me (37 years) is at the end of his career. Completely agree!
“My question is, for that newspaper: in case of the coaches, when and at what point do you see that they are no longer there to lead a team or train?”
Red Devils legend Gary Neville also questioned Mourinho’s ability to lead the club and predicted an imminent sacking.
Speaking to Sky Sports, he said: “Will Mourinho leave? I think it’ll happen.
“My preference would always be to get to the end of the season. But the boardroom is so naive it’s unbelievable.
“To give him an extended contract, knowing his cycle of every three years, was incredible. The minute he came back from pre-season he was at it and the club was out of control.
“18 months he’s 2nd in the league, then you need to keep him hungry.
“His agent was out last week, at press conferences they don’t know what he is going to say next, and they don’t know what to do with him.
“The problem they will have now is he would cost an absolute fortune to lose him, when you lose a manager in the season you have the situation of who comes in?
“It is not just as easy as saying ‘let’s get rid of the manager’ because Manchester United need a reset and it is not just the manager. It’s deeper than that.”
