Sky Sports pundit Jamie Redknapp branded Jose Mourinho 'embarrassing' after he seemed to blame match officials for Chelsea's defeat by Sunderland.
Chelsea's title hopes suffered a major blow after Fabio Borini's late penalty sealed a 2-1 win for Sunderland at Stamford Bridge.
Mourinho appeared to mock referee Mike Dean's performance, despite replays showing that Cesar Azpilicueta made contact with Jozy Altidore in the box, and the Portuguese also pointed the finger at referees' chief Mike Riley.
But Redknapp gave a scathing assessment of Mourinho in the Sky Sports studio, suggesting that the Blues boss should focus on his own failings in the match.
"What he's just said is embarrassing. You're the manager of the team and you're trying to deflect it to the referee," he said on Saturday Night Football.
"They've had a lot of decisions go their way this year, namely the West Brom game and that last minute penalty.
I think he should look at himself and look at his team. Lose at Palace, lose at Villa, lose at Sunderland.

"You've had enough opportunities, you've had enough quality, you've spent enough money this year to beat Sunderland at home and if you don't you've got to look at yourself, you've got to look at your team. There's no point blaming everybody else."
Mourinho had earlier walked away from the post-match interview when asked to expand on his comments, and was equally guarded in the press conference that followed.
"I just want to say four things and I'm sorry because if you ask me more questions, I'll repeat exactly the same thing," he said.
"Congratulations to my players because they gave what they have and what they don't have.
"Congratulations to Sunderland, because they won.
"Congratulations to Mike Dean, because he made a fantastic performance.
"And congratulations to Mike Riley, because what they did during the season was fantastic for the way the championship is going.
"Congratulations to all of them - and I have nothing more to say."
