Everton goalkeeper Tim Howard has had a tough season. The American international was in poor form throughout the campaign and that has seen him lose his place in the Everton first-team to Spaniard Joel Robles.
Howard is therefore being linked with a move back to America. MLS side Columbus Crew have been heavily linked with a move for the player next season - with Howard being a major coup for a side Stateside.
Now a former Premier League and USA international goalie has been having his say on this potential move.
"He'll be the best goalkeeper in MLS. No question.
"He'll be very effective.
"So much of goalkeeping as you get older is kind of how you read the game, how you organize in front of you, and Tim's extremely fit and really hasn't had any major injuries."
He went on to discuss the likeliness of a move, suggesting what Howard had told him about the potential move:
"The last conversations I had with Tim, he was just looking for what felt right at the time.
"If it's right to move back to MLS and the money's right and the situation's right, then cool. If it's not, he's got two years left on his contract. So he's in the driving seat a little bit."
It is looking likely that Everton will move for a new goalkeeper in the summer and Howard's future does appear to be in doubt considering his advancing years and poor form.
It may very well be that his best option is to head back to America and Keller is clearly certain that he would be a hit in MLS.
