Eduardo has expressed his sadness at leaving Arsenal, but has thanked the club for all their help.
The Croatia international ended a three-year stint with the Gunners on Wednesday when he completed a £6million move to Ukrainian champions Shakhtar Donetsk.
The 27-year-old admits it was wrench parting company with the Premier League outfit, especially after they helped to nurse him back to full health following a horrific injury.
Eduardo suffered a badly broken leg during a meeting with Birmingham in February 2008, halting him in his tracks and preventing him from making the most of his time in England.
He has no regrets, though, and believes he can take plenty of positives from the time he spent under the tutelage of Arsene Wenger at Emirates Stadium.
Eduardo told Arsenal's official website: "The past few days have been very emotional for me.
"Although I am excited about the challenge ahead with my new club Shakhtar Donetsk, I am so sad to be leaving my home for the past three years - Arsenal Football Club.
"Arsenal is a very special football club and I will miss so many people - my team-mates, all the staff and, of course, the wonderful Arsenal supporters.
"When I first came to England, I could not speak the language and knew nobody, but as soon as I arrived I was made to feel at home and part of this big family.
"I had some very difficult times with my injury, but Arsenal was always there for me - the medical staff, the management, the players and the supporters. Thank you everybody.
"Although I have now left the club, Arsenal will always be in my heart. I will always look for the Arsenal results and of course, I wish Arsene Wenger and the great players at the club well for next season and the future."
