Everton fans begin to lose faith in Roberto Martinez
The "vast majority" of Everton fans feel Roberto Martinez should no longer be the club's manager, according to a prominent Toffees supporters group.
Martinez's side ended up beaten 4-3 on aggregate by Manchester City after the second leg of their Capital One Cup semi-final on Wednesday, despite having taken a 3-1 lead in the tie early in the first half.
In the Barclays Premier League, they are currently 12th with a record that shows only one win in their last 10 games and just three home victories in the entire campaign so far.
Simon Magner, chair of the Everton Supporters Trust, told Press Association Sport on Thursday: "The feeling among fans from what I've seen over the last couple of weeks is that Martinez has been more and more running out of time with the fanbase.
"Certainly, for a lot of fans, the semi-final was his last-chance saloon.
"I have never known as many people as there are now admitting the time has passed for the manager and it is time for him to move on.
"I think it is safe to say the vast majority of the fans are thinking time is up now and that it is time we tried something else."
While Martinez has complained of late - with Wednesday the latest occasion - about controversial refereeing decisions going against his team, they have conceded plenty of goals to restrict the impact of their frequently-impressive attacking play.
And Magner said: "I don't know what it is, but it doesn't seem to be gelling.
"We look like we could score against anyone, but I think what fans have been increasingly disappointed and annoyed about is that we are making the same mistakes at the back and don't seem to be doing any sort of defensive drilling - because they are basic mistakes.
"Obviously the bad decisions and controversy have played a part. But a lot of fans will also ask 'how many times have we been in winning positions and lost?' We don't seem to be learning from mistakes.
"It's that naivety that is crippling them at the moment and is really dictating the results."
Ex-Wigan boss Martinez has been in charge at Everton since the summer of 2013.
The Spaniard guided the Merseyside outfit to a fifth-placed Premier League finish in his first term, then 11th a year later in a season that also saw them reach the last 16 of the Europa League.
"What he did in the first season was phenomenal, but the second season was a massive disappointment," Magner said.
"He didn't have 100 per cent backing when he came in and I think he won a lot of fans over with the first season.
"But in the second season, I think a lot of them were beginning to feel a little bit vindicated in their opinion of him when he came in."
Everton's derby rivals Liverpool replaced manager Brendan Rodgers with Jurgen Klopp earlier this season, and Magner added: "If you look at other teams who have been in similar positions - Liverpool made a change when their manager wasn't delivering, and they have someone in now with big European pedigree.
"But unless results take a drastic turn for the worse, I can see Martinez still being there in May."
