Tim Howard has signed an extension with Everton through 2018.

The U.S. national team goalkeeper added two years to his current deal with his Premier League club, which was set to expire in 2016.

Howard has helped Everton reach new heights, as the Toffees are challenging Arsenal for fourth place and a spot in the Champions League.

"It is fantastic news," said Everton manager Roberto Martinez. "To have Tim Howard performing as he has been this season, I cannot see past him to choose the best goalkeeper in the league.

"For him, in such an important year with the World Cup around the corner, to commit his future for the long term is an incredible moment for the dressing room.

"I am extremely proud of Tim's achievements for the football club. On top of his goalkeeping it's his overall demeanor and personality in the dressing room. He is a strong leader."
