The Croatian World Cup star is pivotal to the Blaugrana engine room but given the arrivals of Arturo Vidal and Arthur, there is no guarantee that he will get consistent game time this season.
Although the La Liga champions will be reluctant to allow the player to leave, the French giants could launch an offer they can’t turn down.
Rakitic, who joined Barcelona from Sevilla in 2014, has three years to run on his contract at the Camp Nou.
The La Liga champions have been heavily linked with the exciting 21-year-old, although it would take a fee in excess of £50 million (Dhs 234 million) for a deal to go through.
The Dutch U21 star started 25 times for the Eredivisie side last term, scoring one goal and providing one assist in the process. Ernesto Valverde is reportedly keen to sign De Jong as he looks to bolster his midfield ahead of next season.
De Jong, who still has four years remaining on his contract, has also been monitored by Arsenal, Manchester City and Chelsea.
The 25-year-old struggled in the second half of last season, scoring just three times in 22 appearances, leading to increased speculation that he was set to depart West London after just one season.
Despite being linked with Juventus, the Spaniard said his sole focus is making things work out under new boss Maurizio Sarri.
“There was never a thought for me to leave,” Morata said. “For me, it’s easy. I could have gone back to Spain or Italy, all the people believe in me there but I want to change all the things here. I want to, not for all the haters, but for me and for Chelsea.
“I am looking forward to buying a house and I can’t wait for the babies to grow up to put them into school. I am very happy and it’s just the beginning of the new season. Why would I not be happy? I want to change all the thinking from the people who say I’m not.
“It’s the only reason I stay here, otherwise if Chelsea said you are not in our plans, I move.”
