The Spain international has revealed he has already held talks with the Barcelona president Josep Maria Bartomeu about a potential switch to the Nou Camp, just a year after leaving for Stamford Bridge in a £21.4m deal.
It is a huge change of heart for the Spain winger, who told Standard Sport last month that he had no regrets about leaving the La Liga giants and was definitely going to stay at Chelsea next term.
Speaking to BeIN Sports at Spain's camp at Euro 2016, in an interview which has been published by Spanish newspaper Sport today, he said: "Hopefully (I can return to Barcelona) but I know it's hard.
"I have already spoken about it with the president when we were at the (Cup) final (when Barcelona beat Sevilla 2-0 last month) and spoke to all the people who want me there."
"It's complicated, but I've always said that I would like to retire at Barcelona. However, I know it's difficult because the years go by and the club has the best players in the world, it is a very demanding club and to return is complicated. But I do not rule it out either.
"I had been 11 or 12 years in Barcelona, my family is from there and also many friends. The fans loved me, I felt very valued around the club, and it’s always hard to leave the club of your dreams.

"But I have explained before in the end I had to take this decision because I saw that the possibilities (of playing) were low."
Pedro had a mixed first season at Stamford Bridge as injury and loss of form affected performances. However, he still finished the campaign with eight goals from 30 starts.
The 28-year-old, who still has three years left on his contract at Chelsea, won 20 major honours during his career at Barcelona having progressed through the academy.
