They do. That's true.
Too many on here though making the assumption (while not watching him play) that the same has happened to Landon.
I can assure them that it hasn't.
I agree and Cahill was a very different type of player. He was completely fearless, a very physical player. Plus the time he spent flying half way round the world to play for Australia didn't help. He also suffered a lot of injuries in the last few years which took its toll. Donovan is a different type of player, hasn't suffered a lot of injuries and I got the impression from his last spell that he wasn't just relying on his pace anymore. He's a clever player, to me he almost always makes the right decision about which pass to play.
