Barcelona are open to selling the Brazilian this summer as they look to fund other transfers.
The Spanish giants have been unconvinced by Coutinho's productivity since he joined from the Reds for £142m in January 2018.
The 26-year-old accepts his future lies away from the Camp Nou.
One place Coutinho will definitely not land is Old Trafford, according to Sky Sports.
The former Inter Milan man still feels greatly indebted to the Merseyside outfit, where he played for four-and-a-half seasons.
The report also adds that PSG have made contact with Barca over a potential deal for Coutinho.
