I see Pienaar as a player that receives the ball in a standing position and either moves the ball on fast or turns sharply.
His mind os light years ahead of his body.
I see Lennon as more of a headless chicken with pace tp burn. Effective but in a completely different way.
Lennon always chases back with bis pace, while Pienaar just doesn't get forward as much so seems to be in the middle more....i am sure that he used to get slated for his lack of defensive effort too.
