Barcelona's various Twitter accounts were hacked on Saturday with the perpetrators declaring that Paris Saint-Germain forward Neymar will return to the club.
A series of tweets appeared across the club's accounts in different languages on Saturday following the club's 2-1 win over Getafe in La Liga.
One post shared a photoshopped image of Neymar in Barca's latest shirt with a series of question marks and a later post added: "Well, we read some private messages and it look [sic] like Neymar will be back here."
Neymar has been linked with a return to Barca since he left for PSG in 2017 and he came close to re-joining the club last year. Sources have told ESPN that the Catalan club are considering making a renewed attempt to sign him this summer.
Another tweet from the hackers called for the club's president, Josep Maria Bartomeu, to resign, while another one saw the group known as OurMine take responsibility for the posts.
It's the second time the group has taken over Barca's Twitter accounts and the third time the Spanish champions have been hacked -- activists claiming to be the Syrian Electronic Army managed to post a series of tweets in 2014.
"Hi, we are OurMine," said another post on Saturday by the group that has previously taken over the accounts of a number of companies, including Netflix, HBO and Playstation.
"Well, this is the second time, the security level is still not the best."
Barca quickly deleted the posts before confirming they had been hacked in a short statement.
"FC Barcelona's Twitter accounts have been hacked, which is why messages from outside our club have appeared, and which have been reported and deleted," the club said.
"We will conduct a cybersecurity audit and will review all protocols and links with third-party tools, in order to avoid such incidents and to guarantee the best service to our members and fans. We apologise for any inconvenience this situation may have caused."
