The Catalan giants have been one of the biggest forces in world football over the past decade, winning six La Liga titles and three UEFA Champions League crowns during that time.
Mascherano, though, believes such cycles in football are destined to eventually come to a halt and admits the situation at Barcelona should be no different.
“Barca’s period of success is coming to an end, I am certain,” Mascherano told El Grafico.
“It is not over yet but I know this will soon be over, as happens to every top club and successful cycle of players, it does not last forever.
“I believe I know when it will be over, but I am not telling you that.”
