Liverpool is interested in Alexis Sánchez and could submit a bid worth nearly $45 million.
Juventus and Manchester United are also interested in Sánchez.
Sánchez is playing a starring role in the World Cup for Chile, but has often been under-utilized for Barça.
Sanchez has scored 39 goals in 88 appearances for Barça since arriving from Udinese in 2011.
