Philippe Coutinho has had a difficult year in Spain and has been heavily linked with a transfer this summer.
The Brazil international left Anfield for Catalonia in January 2018 for a reported £142m deal but has seen his future attract widespread speculation in recent months.
However, Coutinho returned to goal-scoring form in the Champions League on Wednesday as Barcelona secured their spot in the quarter-finals of the competition.
Speaking after Barcelona's 5-1 drubbing of Lyon, Coutinho admitted his form has been sub-par and vowed to do better - but stopped short of committing his future.
Speaking to
Calcio Mercato , 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."
Having fallen behind Ousmane Dembele in the Barca pecking order, the 26-year-old has only managed to play a whole match on just nine occasions for his club side this campaign.
