The Qatari club loaned the Brazilian until the summer.
Earlier this winter, there have been reports that Inter Miami are looking for Coutinho.
The MLS club has previously signed Lionel Messi, Sergio Busquets, Jordi Alba and Luis Suárez.
Coutinho has played with all four at Barcelona. Now he addresses the rumors of a possible reunion.
– I only think about the present. I want to feel good, prepare well, play good matches and enjoy my football, says Coutinho to Sport and continues:
My name always appears in the papers where they talk in every way.
– We never know what will happen in the future. My name always appears in the papers where they talk in every way, good and bad. I try not to follow it and I just think about doing my job well and enjoying myself.
The 31-year-old has scored four goals and one assist in ten competitive matches for Al-Duhail.
Coutinho’s contract with Aston Villa runs until the summer of 2026.
