The 30-year-old full-back, who is comfortable on both the right and left flanks, is rumoured to be assessing his future at the Nou Camp after struggling for game time this season.
This has alerted the Reds, who have put him on their list of potential transfer targets for later this year.
Adriano himself has confessed that he will assess offers, making him a tempting option for the Merseysiders as Glen Johnson’s contract ticks towards its end.
The South American has a release clause of close to £15m in his contract, but a fee of around half of that is likely to be enough to sway Barca.
Adriano is confortable at either right or left-back and can also play in a more advanced role thanks to his pace.
