Ronaldo, 38, took his stance as though he was going to produce one of his trademark knuckleball free-kicks.
And Al-Wehda keeper Munir Mohamedi was clearly preparing for the Portuguese legend to step up as he began to move to his left.
But Telles, who left Man Utd for Saudi Arabia in the summer, whipped the free-kick the other side of the wall to give Al-Nassr the lead in the 11th minute.
But it should not have come as too much of a surprise as Ronaldo’s free-kick record over the past decade is poor.
He has scored just five since the start of the 2019/20 season and 10 since the 2014/15 campaign – despite usually being first in the queue to take them.
