The Spanish giants have had three huge bids for Coutinho rebuffed by Liverpool, the last coming in at a colossal £114m.
Ernesto Valverde's side are now ready to throw in the towel and turn their attention to potential alternatives.
There may only be two days left of this summer's transfer window, but the mentioned source claims that Barcelona are eyeing up a sensational move for one of Atletico Madrid's Griezmann, Juventus' Dybala or Monaco's Lemar.

Dybala is currently one of the most sought after players in Europe and has been linked with the Catalans ever since Neymar completed his world record move to PSG.
Griezmann is another name that has been surrounded by speculation this summer. If it weren't for Atletico's transfer ban, the Frenchman may have already left the Madrid club.
Lemar completes the three-man shortlist, but a deal is very unlikely as Liverpool officials flew out to Monaco on Tuesday in an attempt to finalise a deal with the winger, meaning the Reds are very much in the ascendancy for his signature.
Can Barcelona add to their squad before tomorrow evening?
