The Brazil international spent four seasons at Barca before his move, including winning a treble in 2014-15.
Suarez said he would be happy to see Neymar, who is sidelined with an ankle injury, back at Camp Nou.
"I was privileged to fulfil one of the best years of my life as a football player at Barcelona next to the best in the world, Messi, and the second best in the world, Neymar," the Uruguay international told RAC1 on Monday.
"For me, it was one of the best moments I've ever lived, won the treble."
Suarez added: "Who would not want to enjoy players like Ney?
"But he belongs to PSG and these are things that are always talked about during the market."
