Coutinho, who joined Barca from Liverpool a little over a year ago, has been linked with a move away from the La Liga giants after struggling to nail down a regular starting spot in Ernesto Valverde's team.
A return to the Premier League has been mooted with Liverpool, Chelsea and Manchester United viewed as possible destinations.
Asked about his future and Neymar by De Sola, Coutinho said: “It's always a pleasure to play with him, it's a crack. We played a lot of time in Brazilian youth teams, [Neymar] became a special player.
“Playing at his side is always a pleasure, even though I haven't had any luck at the club level yet. It would be nice to play with him in a club."
