Goalkeeper Tim Howard has signed a two-year contract extension that will keep him at Everton until 2018.

The goalkeeper, 35, has been a mainstay of Roberto Martinez's side this term as they have pushed for a Champions League place.

Everton boss Roberto Martinez praised Howard’s impact on the club and hailed him as a role model.

"He has been vital to our overall achievements,” Martinez said. “It’s not just about his performances. He is a unique role model."

The deal will keep Howard at Everton until he is 39, and may allow him to amass over 500 caps. He would be the fourth player in Everton’s history to do this.

Originally signed on loan from Manchester United in 2006 before making the move permanent in early 2007, Howard has made a major impact for the Toffees.

He has kept 116 clean sheets in the Premier League, the 10th highest total in the competition's history.

Everton are fifth in the Premier League standings with 66 points from 34 games, a point behind Arsenal who occupy the last Champions League qualifying spot with four games left.
