Willian has confirmed he is leaving Chelsea after the expiration of his contract, with the Brazil international seemingly edging closer to joining Arsenal.
The playmaker joined Chelsea from Shakhtar Donetsk in 2013, going on to make 234 Premier League appearances for the Blues.
However, after winning two league titles, one FA Cup, the EFL Cup and the Europa League, Willian is leaving Stamford Bridge after failing to agree to a new deal.
In an open letter to Chelsea's fans on Sunday, Willian penned an emotional goodbye to the club.
"They were seven wonderful years," he wrote. "In August 2013 when I received the offer from Chelsea, I was convinced that this was where I had to play.
"There were so many happy times, some sad, there were trophies and it was always very intense.
"I am really grateful to the Chelsea fans for the affectionate way they welcomed me to Stamford Bridge and their support throughout my time at the club.
"The time has now come to move on. I am certainly going to miss my team-mates. I will miss all of the staff at the club who've always treated me like a son and I will miss the fans.
"I leave with my head held high, safe in the knowledge that I won things here and I always did my best in a Chelsea shirt!"
Willian's agent Kia Joorabchian revealed last month that his client had offers from two Premier League clubs, with Arsenal the favourites to land the 32-year-old.
Pedro also left Chelsea on Sunday, and is set to join Roma on a free transfer.
The Spanish forward is out of contract with the Blues and is rumoured to be heading for Italy next, reportedly to join Serie A side Roma on a two-year deal.
His final appearance for Chelsea came to a painful end, as he suffered a dislocated shoulder during the FA Cup final loss to Arsenal. He has since undergone surgery on the injury and did not feature in the Champions League defeat to Bayern Munich on Saturday.
In an Instagram post on Sunday, Pedro reflected on his successul time at Stamford Bridge, thanking all those who helped him feel at home following his move from Barcelona in 2015.
"After five wonderful years my stage at Chelsea comes to an end," he wrote.
"Thanks a lot to the club's board, to the coaches and team-mates I've had, and of course to the fans: thank you for the experience of being a member of your big family. I've been very happy here, you've made me feel like home.
"It's been a pleasure and an honour to play for this club and win the Premier League, FA Cup and Europa League titles, as well as competing in one of the world's best football leagues.
"I made the right choice, I take with me wonderful and unforgettable memories."
Pedro was part of Antonio Conte's Chelsea squad who secured the Premier League title in the 2016-17 season, while he also won the FA Cup and the Europa League with the London club.
