After Neymar moved to Paris Saint-Germain last summer, Coutinho was immediately identified as one of a handful of targets to replace him, but Liverpool refused to sell in August, at which time Coutinho missed games due to "injury".
It is this aggressive transfer policy of club that is cited as one of the reasons, why Liverpool had made a decision to insert a three year clause in the Coutinho deal, in order to prevent their interests against the lure of Barcelona, Sportreports.
The information, revealed by the show "Què t'hi jugues" on Cadena Ser, explains that when the two clubs agreed the €160 million deal for the Brazilian worldwide, Liverpool wanted to include a pact that would prevent Barça signing any of their other players.
The previous summer they warned Barcelona not to make any more approaches for him or they would be reported to Federation Internationale de Football Association.
According to the Daily Mirror, Barça have £36m left to pay off to the Reds, but that is all dependent on how the 26-year-old Brazilian performs over the course of his career at the Camp Nou.
Mohamed Salah, who enjoyed a fantastic season for Jurgen Klopp's side last term, has been linked to a move to Barcelona.
And it has now emerged they were initially agitated by Edwards' insistence on the clause being inserted but were forced to agree to it if they wanted Coutinho. They had earlier recruited Luis Suarez from the Merseysiders.
