Paris Saint-Germain attacker Neymar is reportedly desperate to seal a return to Barcelona.
Neymar, 26, scored 105 goals in 186 appearances for Barca between 2013 and 2017 before completing a world-record move to PSG in last summer's transfer window.
The Brazilian has netted 39 times in 41 appearances for PSG since his arrival, but suggestions that the attacker is unsettled in France have gathered pace in recent months.
According to Mundo Deportivo, Neymar 'misses life at Camp Nou', and is also unhappy at the constant attention surrounding Kylian Mbappe, who has been outstanding since his arrival from Monaco.
Neymar won two La Liga titles, three Copa del Rey crowns and one Champions League at Camp Nou.
Ousmane Dembele - signed to replace Neymar - has scored five times in 10 appearances for Barca this term.
