Martinez has generally avoided criticising his players after matches this season, and he has a tendency to over-exaggerate.
With the Toffees failing to live up to expectations, Martinez’s hyperbolic statements to the media have become heavily focussed on by supporters.
And Redknapp believes that Martinez simply has to lead Everton to a semi-final victory over Manchester United in the FA Cup if he wants to relieve the pressure on him.
“I’m a big fan of his but the problem is the supporters don’t always see what he sees,” the former Queens Park Rangers boss said. “You can hear them thinking: “Hang on, you keep saying we played well but we’ve lost again.”
"There are only so many times you can say that before the fans lose patience with you. Getting thrashed at Liverpool last night will make it even more important they come through."
Everton go into the FA Cup semi-final on the back of a heavy defeat against their Merseyside rivals Liverpool.
Martinez’s side were demolished by the Reds last night, and they will need to put in a much better performance against Wembley if they are to make it through.
In fairness to Martinez, he was very critical of Everton’s display at Anfield, but the pressure is mounting on him.
The calls for Martinez to be sacked are only growing louder, and if Everton are beaten at Wembley then the Spaniard will be in serious danger of losing his job.
