A naturally gifted right-back, Sagnol's caps in that position have been limited by Lilian Thuram.
Thuram has long been Roger Lemerre's preferred right-flank defender and that looks unlikely to change immediately.
At 24, though, Sagnol has time on his side.
He has been an impressive force for Bayern Munich on the opposite side of the field from Bixente Lizarazu since joining the club two seasons ago.
He enjoys the attacking approach that Lemerre preaches and will be an excellent substitute at the very least.
