Cesc Fabregas has paid tribute to former manager Arsene Wenger after securing his move to Barcelona on a five-year deal.
The end to the long running transfer saga sees the 24-year-old rejoin the Nou Camp club until at least 2016, with an £175 million buy-out clause attached to his contract.
The Spanish World Cup winner underwent a two-part medical on Monday ahead of signing for Barca, in a deal reportedly worth £35 million.
Fabregas said: "I'll never have enough words to thank him (Wenger) for all he's done for me. I'll never forget him.
"I don't think he has such a good image here, he has been portrayed as something he's not, in my opinion. I can't express my admiration for him strongly enough, I owe it to him that I am here."
Despite going the last six seasons without winning a trophy, Fabregas became the fulcrum of Wenger's exciting Arsenal side which sparkled domestically and in Europe.
After leaving the Catalans in 2003, Fabregas flourished in The Gunners' midfield as he became a household name in the Barclays Premier League.
He was handed the captaincy at The Emirates Stadium at just 21 years old in 2008, but the clubs' failure to add to the FA Cup they won in 2005, the only major honour Fabregas claimed while at the club, played a major part in his eventual departure.
On the loss, Wenger said: "We have lost a world-class player but many big players have left and the club went on."
