While I think is vital for a player to be versatile. I believe being a specialist in a postion is more important. A comparison can be drawn with the difference between a doctor that is a general practitioner and a obgyn.
Both are doctors and both can treat you but the one has a greater expertise and skill in his chosen field.
That being said Francois has already played the yo-yo game between positions and he himself has said that his game suffered because of it. He is also on record as saying when he played for a team which utilized him in his preferred position he played better and considered himself a better player.
I think that Frans should play in the position he is best suited to play and most comfortable in to maximize his potential.
