Paris Saint-Germain's director of football Patrick Kluivert refused to rule out the possibility of Lionel Messi playing for the French champions.
Messi's Barcelona contract does not expire until 2018 but the five-time Ballon d'Or winner's future at Camp Nou is far from certain.
While team-mates Luis Suarez and Neymar have signed new deals, Messi is no closer to renewing with the LaLiga titleholders.
And Kluivert added fuel to the fire after PSG routed Barcelona 4-0 in the first leg of their Champions League last-16 tie on Tuesday.
"Messi? Never say never," Kluivert told reporters post-match in Paris.
"Every team wants a player like Messi."
Messi and Co. struggled as PSG left Barcelona on the verge of elimination.
The 29-year-old has scored 32 goals in all competitions this season.
