Although unable to unlock the right combination of forwards to provide goals, Santos has had a respectable campaign as Greece coach.
Getting through the group stages was a phenomenal achievement, and his side were inches away from the quarter-finals of the World Cup.
His selections have by and large been impressive, particularly following the exclusion of Kostas Katsouranis against Japan.
With Katsouranis unavailable to him when facing the Ivory Coast, he turned to Lazaros Christodoulopoulos, who provided more dynamism in midfield. Andreas Samaris' arrival for the injured Panagiotis Kone saw Greece produce their best football of the tournament, and Santos stuck with the pair for the game against Costa Rica.
He may rue his decision to include Katsouranis in the starting line-up against Japan, and he could perhaps be accused of overrotating his forward line.
However, he coached a team that showed more attacking intent than his predecessor's, whilst retaining a solid platform in defence.
Having qualified for two major tournaments and navigated the group stages of each of them, he can certainly leave with his head held high.
