The France international joined the Bianconeri this summer from Paris Saint-Germain, having also previously been linked with a move to Barcelona.
However, he has now found himself in a crowded midfielder at the Old Lady and has started just two matches to date across all competitions.
Calciomercato now draw on reports that the 24-year-old is already considering an exit route from the Italian champions, with the Blaugrana now back on the agenda for the player.
Indeed, it has been claimed Rabiot’s representatives have already held informal talks with the Catalan giants in an attempt to lay the groundwork for a potential move, the report adds.
