English news outlet 'BBC Sport' reports that the 25-year-old is still Ernesto Valverde's top target as the British transfer window ticks into its final 24 hours.
Coutinho has been linked with a move for Spain almost all summer and speculation only intensified following Neymar's move to PSG.
Barca are thought to have had three bids for the player turned down, with Liverpool adamant that the Brazilian will not be leaving the club this summer.
Despite Liverpool's assertions, there has always been a feeling at the Camp Nou that Barca would get their man eventually, though that confidence is beginning to fade, thus why the club are considering alternatives.
One such possibility is Monaco winger Thomas Lemar who is currently the subject of serious interest from Liverpool. Barca are also thought to hold a long-standing interest in Juvetus forward Paulo Dybala, but for now coutinho remains their priority.
Following last week's signing of Ousmane Dembele from Borussia Dortmund, the Catalans' technical director Robert Fernandez admitted that they were hoping to make further reinforcements before the deadline, saying: "I won't go into names but I admit that the club is working on the possibility of signing new players."
Either way, Ernesto Valverde's side have until 23.00 BST on Friday to add the finishing touches to their squad, with the Spanish transfer window closing 24 hours later than the British one.
Will Coutinho get his move after all?
