Everton midfielder Tim Cahill has completed his move to Major League Soccer side New York Red Bulls, subject to international clearance.
The fee is believed to be in the region of £1m for the 32-year-old.
The Australian spent eight years at Goodison Park, scoring 56 goals in 226 league games.
"We are absolutely thrilled to bring in a player of Tim's calibre ," said New York Red Bulls general manager and sporting director Erik Soler.
"He is the technical, physical presence we have been looking to add in our team and he brings a wealth of experience to our club having played in some of the highest levels of international soccer," he added.
Cahill, who joined Everton in 2004 for £1.5m from Millwall, said: "I am very happy to start a new chapter of my career with the New York Red Bulls.
"I also want to thank everyone at Everton, from the club to tremendous supporters. It has been a privilege to be an Everton player for the past eight years and it was a very difficult decision to leave."
The club will officially introduce Cahill to the media at a press conference on Monday.
Cahill moved to England in August 1997, joining Millwall from hometown side Sydney United on a free transfer.
The Australian scored three goals in Millwall's run to the FA Cup final, including the winning strike against Sunderland in the semi-final. The London side lost 3-0 to Manchester United in the Millennium Stadium final.
An attacking midfielder, he made his international debut in 2004 and has played for Australia at the last two World Cups in Germany and South Africa.
Cahill, who signed a four-year contract with the Toffees as recently as May 2010, was a fans' favourite at Goodison Park but only scored three goals last season after going the whole of 2011 without finding the net.
