Former Everton ace Cahill, who played briefly with Donovan during the USA internationals loan stints at Goodison Park, knows what it feels like to carry the weight of a nation on his shoulders and he hopes that the Galaxy skipper can simply embrace that.
"Listen, I'm blessed to be a footballer," said Cahill from the Desert Diamonds Cup on the weekend. "All I can say is people have to get up and go to work at 5 in the morning, like my parents.
"I always forget the hardship of people, what they go through mentally.
"You've got to put things in perspective. [Donovan's] got the world on his shoulders. It's not a bad thing to have on your shoulders, is it?
"It's a compliment when everything's thrown at you. When something goes wrong, it's your fault."
He added: "You have to question why you play football. If it's not for the right reasons, then stop. But if it is, then continue. He's a good kid. He knows what he can do and what he can't do, so I would just look at putting life into perspective. We've got a great job in the MLS. That's the way I look at things."
