Barcelona winger Pedro is unsettled at the Camp Nou, according to his agent Francois Gallardo.
The 26-year-old has had to compete with Neymar and Alexis Sanchez for a place in Gerardo Martino's team this season.
Pedro is said to be considering his future at the Catalan club, having started just three of Barca's 10 Champions League matches this term.
Gallardo is quoted by the Daily Star as saying: "Pedro is very angry this season.
"The player is in a difficult situation and may be sold, although that could be a bad move for Pedro."
Manchester United, Manchester City and Bayern Munich are reportedly among a host of clubs that are interested in capitalising on Pedro's frustration at Barca.
