Barcelona will reportedly offer Alexis Sánchez and £56 million to Liverpool for Luis Suárez.
Sánchez has received interest from Juventus, Atlético Madrid, Arsenal and Manchester United.
The inclusion of Sánchez makes the move for Suárez economically viable for Barcelona.
Suárez had an outstanding season at Liverpool, but is believed to be strongly interested in a move to Spain. Real Madrid also has interest in Suárez.
