Thuram is a centre back, but in Euro 2000, I think, he was asked by the national coach to play right back and he did. He played very good as right back and when juventus bought him it was to play right back, but technically he is a central defender.
And he is no left back.
Wtf is m_elayyan on about? Thuram has never played a game at left back in his entire career, I'm sure. At Parma he played RCB in a three man defence IIRC, but he was transformed into a RB for the French NT. When we bought him he stated that he preferred to play in the centre but we needed a right back and therefore that's where Lippi played him.
PS. Thuram played CB for Santini's France at Euro 2004.
Thuram was a CB when he played for Monaco and RCB. On a practical note, RCB is really a CB, that concentrates on man-marking.
The reason he played RB for France, IMO, is that French already had Desailly (A terrific player in his prime) and Laurent Blanc (Ditto), and they formed tremendous partnership so basically there was no room for Thuram to play in that position.
If anything, with loss a yard to two in pace, I think Thuram is better off playing CB than as a full-back right now.
