Willian has confirmed he is leaving Chelsea, with Arsenal close to completing his signing on a three-year deal.
The Brazilian has written an open letter to fans confirming his exit following Chelsea's defeat to Bayern in the last 16 of the Champions League.
The 32-year-old leaves Stamford Bridge at the end of his contract after a seven-year spell, with Chelsea only willing to offer him a two-year deal rather than the player's desired three years.
"They were seven wonderful years. In August 2013 when I received the offer from Chelsea, I was convinced that this was where I had to play," he wrote.
"Today I am certain that it was the best of decisions. There were so many happy times, some sad, there were trophies and it was always very intense.
"Yet, beyond the trophies, I learnt a lot about myself. I developed a great deal, becoming a better player and a better person.
"With each training session, with each game, with every minute spent in the dressing room, I was always learning.
"I am really grateful to the Chelsea fans for the affectionate way they welcomed me at Stamford Bridge and their support throughout my time at the club.
"There was also criticism, which is normal, what is important though is that both the affection and criticism drove me to always give my all in every training session, every game, to be constantly improving until my very last minute in a Chelsea shirt.
"The time has now come to move on. I am certainly going to miss my team-mates. I will miss all the staff at the club who've always treated me like a son and I will miss the fans."
