Torres' rediscovery of decent form under his old mentor has not surprised Rodgers at all.
He said: "The only thing missing with Fernando has been confidence. He has not lost his quality.
"He was arguably one of the best strikers in the world for 18 months at Anfield. Then he had a setback, an injury, and never really regained the heights.
"But maybe that was the first setback he's ever had. It's why I always judge young players after they've had a trauma."
