Coach Xavi Hernandez said Tuesday his Barcelona team must be rebuilt after a turbulent season but refused to be drawn on whether Robert Lewandowski was a transfer target.
The Catalan giants finished 13 points behind La Liga champions Real Madrid, their campaign ending in a whimper on Sunday with a 2-0 home defeat to Villarreal.
Barcelona were beaten in four of their last nine games in all competitions.
They were on a plane the next morning for their first-ever match in Australia, a friendly against an A-League All-Star team coached by former Manchester United striker Dwight Yorke and captained by former Manchester City defender Jack Rodwell.
