Former Everton goalkeeper Nigel Martyn is backing Tim Howard to play into his 40's.
The former Manchester United keeper has previously hinted that he may retire from football at the end of his current contract with Everton which ties him to the club until 2018, when he will be 39.
Martyn told the Liverpool Echo: "How long Tim can keep playing is down to his form and if he stays clear of injury.
"Also how he feels mentally is important as well.
"It is slightly easier for an English guy to stay in England and carry on playing.
"I don't know whether Tim would want to finish his career back home and play a couple of seasons in the MLS. But as long as he wants to do it and stays clear of injury then Tim can easily to play until he is 39 or 40.
"It is a season by season or even a six-month by six-month thing.
"But look at Mark Schwarzer, he has just been given a new contract by Chelsea at the age of 41. They trust him and are happy to rely on his experience."
