Tim Howard could leave Everton in the summer.

Roberto Martínez believes the 36-year-old’s strong performances, such as in the Boxing Day win at Newcastle United, are being overlooked and that the goalkeeper merits more appreciation.

“I don’t think he was being sarcastic,” said Martínez of the veteran’s recent exchanges with the Goodison crowd. “He cares about our football club and has an incredible attachment to it. He is trying to interact with the fans with the experience he has. Tim would never blame a defender for his mistake and I appreciate that. Tim has got 350 appearances in the Premier League which is a record for Everton. He is part of our club and our badge.

“He had mistakes but he had big moments. We need to be more understanding that sometimes you’re going to get that. His day-to-day work shows me the strength, power and positive effect he has on young players. I feel we are a stronger team with Tim Howard in the dressing room.”
