The Nou Camp star completed his sensational £200m move to Paris St-Germain last night.
Barca are keen to replace the winger this summer and Brazil international Coutinho has been heavily linked with the La Liga giants.
And BetStars say the Liverpool star is odds-on to join Barca in the coming weeks.
BetStars director of trading Ian Marmion said: “Barcelona look to have set their sights on Liverpool’s Philippe Coutinho as the player to reinvest part of the world record sum generated by his Brazilian compatriot Neymar.
“The 25-year-old midfielder has been lined up as a long-term replacement for club veteran Andres Iniesta in midfield and also possesses the Brazilian flair similar to that of Neymar.
“The odds of a deal have been slashed from 2/1 to 8/11 following his fellow countryman’s impending move to Paris with Coutinho now priced at odds-on to make the switch to the Nou Camp this summer.”
Liverpool are desperate to keep hold of Coutinho, 25.
Jurgen Klopp wants to keep his squad together with Champions League football returning to Anfield next season.
The German has already landed Mohamed Salah, Andrew Robertson and Dominic Solanke this summer.
