Almost amusing how he signed for the length of Mbappe contract. They must have sat there since Christmas trying to talk him into something longer.
Got nothing to do with Mbapp? even if as a Real Madrid you care more about him.
It is also the length of Neymar contract. One could say it coincides with Qatar WC and could signal the end of PSG project from the Qatari overlords.
Realistically, his contract mirrors the latest contracts signed by PSG managers recently. Laurent Blanc signed for 2 years, Emery signed for 2 years, Tuchel signed for 2 years, Pochettino is signing for the same duration (6 months less due to his arrival in January obviously).
It is about reducing the risk in case of failure.
