Steyn had to move to flyhalf in the Sharks' Super Rugby clash against the Lions at Ellis Park last Saturday after Fred Zeilinga was forced off with a hamstring injury.
The Springbok had a stellar game, helping the Sharks to a 25-12 win.
In the post match interview, Du Plessis labelled Steyn as the best player he's ever played with.
It was not clear whether Du Plessis was referring to Steyn's cannon-boot which turned the course of the game with two massive penalties in the second half, or Steyn’s general play, but it was nevertheless high praise...
