Pedro joined Chelsea in August 2015, after a successful seven-year career at his boyhood club Barcelona where he won 20 trophies with the first team.
After a forgettable first season in England which ended in Chelsea’s catastrophic title defense, Pedro helped Chelsea to their fifth Premier League title under Antonio Conte, scoring nine and providing ten assists in the process.
The Spaniard was also key to the side that won the Europa League under Maurizio Sarri against Arsenal in Baku.
Having been limited to only eleven league games last season, Pedro opted to join Roma after his contract with Chelsea came to an end this summer.
The 33-year-old took to his Instagram and Twitter account on Sunday morning to reflect on his Blues career and thank those who have played a part in it.
‘After five wonderful years my stage at Chelsea FC comes to an end,' Pedro wrote.
'Thanks a lot to the club’s board, to the coaches and teammates 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.
'I say farewell very pleased with this stage of my career, and I'm also very excited with the next to begin. Thanks and good luck for the future.
'Come on Blues!!! ?? @ChelseaFC #KTBFFH #CFC'
Pedro scored 43 goals and provided 28 assists in 206 matches during his time with Chelsea.
