New Barcelona chief Ariedo Braida says only two clubs could prise Lionel Messi away from the Nou Camp. Messi has been linked with Manchester United and Chelsea.
But Braida says: "I think it's almost impossible for him to leave Barcelona.
"But with Paris Saint-Germain and Manchester City having so much money that could happen. Sometimes these strange things happen.
"He is a phenomenon, an extraterrestrial comparable to Maradona and Pele."
