Barcelona are determined to sign Adrien Rabiot - as an act of revenge on PSG.
Off contract in June, it has been confirmed by PSG management that Rabiot will spend the rest of the season in the stands as he refuses to consider talks over a new deal.
Barca are keen and a source told France Football: "They are interested in Rabiot, of course, but they also want to take a shot at Paris.
"There is an open war between the two clubs. Barça approached Thiago Silva, Marquinhos, Verratti and then it was necessary to extend and re-commit them. Then there was the episode of Neymar.
"Now, that's the reason for the Rabiot assault."
