The Red Bulls declined to pick up their contract option on the 35-year-old striker, who had been its team captain.
Angel has not said if he plans to return to the MLS. He reportedly is considering a return to play for the Colombian international team.
He became expendable when the Red Bulls, which had a new general manager and coach, added high-profile international players for high price tags. He earned nearly $2 million in 2010, according to MLS Players Union.
After a match in September -- ironically, against the Galaxy -- Angel seemed to see the writing on the wall.
"I have enjoyed my time here tremendously," he said. "With the players we have, this is the best squad. Whatever happens, I will wish the team well and move on."
The question now is, move on to where?
