The influential midfielder turns 32 in January 2012 and is slowly nearing the end of his playing career.
But Nadal does not expect the Barcelona star to leave the game once he hangs up his boots.
"Whether I can see Xavi following the same career path as Pep Guardiola? Well, obviously you never know what will happen in the future," Nadal was quoted as saying by Sport.
"It would not really surprise me if Xavi became a coach in the future though. He really loves football, and I don't think he'll leave the football world after his retirement.
"It all depends on what he wants to do, but he surely has the football philosophy to become a success on the bench."
Xavi's current contract at Camp Nou runs until the summer of 2014.
