Roberto Martinez responds when asked whether he'd discussed Everton supporters' criticisms with Farhad Moshiri

Everton supporters have grown frustrated with Roberto Martinez's management of their side this season.

Roberto Martinez has told Everton’s official Youtube channel that he has not spoken to Bill Kenwright or Farhad Moshiri about supporters’ criticisms.

Toffees supporters have heavily criticised Martinez in recent weeks, and a banner was unfurled demanding for him to be sacked in the Merseyside club’s most recent match against Watford.

Everton fans have grown frustrated with the Spaniard’s inability to maximise the potential of their talented squad and the pressure is growing on him to start delivering.

With new investment coming in from Moshiri, expectations are rising at Goodison Park and their current position of 14th place in the Premier League is becoming unacceptable.

However, Martinez insists that when he has spoken to Kenwright and Moshiri their focus has been entirely helping the side win their next match, which comes against Crystal Palace tomorrow.

"The conversations are on a day to day basis and trying to improve every aspect," he said. "As you can imagine, we have so many matches at the moment that the only focus on matters is preparation for the Crystal Palace game."

Everton were expected to challenge for a European spot this season, but they have badly underperformed.

Martinez’s men have never really threatened the top six, and their recent slide down the table has been extremely worrying.

If Everton are to lose to Palace tomorrow, they would fall into 15th place in the top flight standings, leaving Martinez’s position looking even more insecure.
