Lionel Messi says he would be happy if Neymar is returned to Barcelona because it would help increase the chances of achieving the club's objectives.
Neymar, 27, joined Paris St-Germain from Barcelona in 2017 for a world record fee of 222m euros (£200m).
"He was desperate to come back," Messi told
Spanish newspaper Sport. "I don't know if the club really tried or not."
Neymar scored 105 goals in 186 games for the Catalan club between 2013-2017, and has 51 goals in 58 games for PSG.
