Luis Suarez said the decision to leave Liverpool for Barcelona was made "with a heavy heart" and wished the team and manager Brendan Rodgers "well for the future".
In a statement posted on Liverpool's website, the Uruguayan striker said: "It is with a heavy heart that I leave Liverpool for a new life and new challenges in Spain. Both me and my family have fallen in love with this club and with the city.
"But most of all I have fallen in love with the incredible fans. You have always supported me and we, as a family, will never forget it, we will always be Liverpool supporters.
"I hope you can all understand why I have made this decision. This club did all they could to get me to stay, but playing and living in Spain, where my wife's family live, is a lifelong dream and ambition. I believe now the timing is right.
"I wish Brendan Rodgers and the team well for the future. The club is in great hands and I'm sure will be successful again next season."
The statement finished with Suarez saying: "You'll Never Walk Alone".
