The Spaniard completed a transfer from Barca to Stamford Bridge last summer for a fee believed to be around £21 million, but after just one season, he is already being linked with a swift return to Spain.
Pedro left the Catalan club after falling down the pecking order behind the infamous trio of Lionel Messi, Luis Suarez and Neymar, but his debut season in the Premier League hasn't gone as expected.

After ignoring interest from Manchester United, the Spanish international chose to join Jose Mourinho's Chelsea, and he went on to make 29 Premier League caps, with five of them being substitute appearances, for the Blues, contributing with seven goals, as per Soccerbase.
The Spaniard had to battle for a starting spot at Stamford Bridge, with the likes of Willian, Oscar and Eden Hazard all competing for an attacking midfield position.
It was a season to forget for the Blues as they went from Premier League champions to a 10th-placed finish, a whopping 31 points off eventual winners Leicester City.
After a troublesome start to the new campaign, Mourinho became a Roman Abramovich casualty for the second time in his managerial career, being replaced by interim manager Guus Hiddink, who was also appointed for a second time by the Russian owner.
Chelsea will be guided into a new era next season, with current Italian manager Antonio Conte taking over after the European Championships in France.
Upon arriving at Stamford Bridge, one of Conte's first jobs may have to be to hold talks with Pedro and resolve his future.
Pedro confirmed last week that he would love a return to Barcelona this summer, but it seems his desire to return to the Nou Camp could be a dream rather than a reality, as he has now confirmed that a move back to Spain would be 'almost impossible'.
He said: "If you ask me if I'd go back, the answer is clear because they're a great club with great players and fans who appreciate me.
"I've always said that I'd like to retire at Barca, but I know it's very difficult, almost impossible.
"Admittedly it seemed like I was going back this summer, but I have a contract with Chelsea. I've only been there for a year and it'd be very difficult for [a return] to happen."
The 28-year-old has already spoken to Barca president Josep Maria Bartomeu about a possible return to the La Liga champions, but when asked about that discussion, Pedro revealed that they were discussing the team, rather than a possible transfer.
"We talked about the team, not me.
"When I left, he told me that the doors of the club would always be open and I said that was very important for me because [Barca] are a club that I can feel. It's where I grew up and was happy."
Pedro was a product of Barca's famous youth academy, and during his time with the Catalan giants, he made 181 La Liga appearances, with 54 of them being as a substitute, scoring 58 goals.
The winger has had a glittering career so far, with the majority of his honours coming from his time with Barcelona.
He has won five La Liga titles, three Copa del Rey trophies, three Champions Leagues, three UEFA Super Cups and two FIFA Club World Cups.
Pedro is also an established figure in the Spanish national side, making 56 appearances, and helping them to one World Cup and one European Championships.
