According to The Athletic, Liverpool were also looking at re-signing Coutinho at the time.
However, the discussion wasn't a long one because Barcelona wanted a staggering £8million loan fee, as well as Coutinho's £250,000-a-week wages paid in full, and Liverpool were not prepared to stump up such a sum to sign him.
A number of top clubs including Manchester United and Tottenham considered bringing the Brazilian in for the season before Bundesliga giants Bayern Munich finally won the race to sign him temporarily.
Jurgen Klopp reportedly sat down with Liverpool sporting director Michael Edwards in the summer to discuss re-signing Philippe Coutinho.
The Barcelona midfielder left Liverpool for the Camp Nou in January 2018, putting pen to paper on a lucrative deal after completing a £142million switch.
But it became clear after Coutinho's first season that game-time was going to be difficult, after the midfielder failed to set the world alight in Spain, and Barcelona made him available for loan.
