#4 Worst - Willy Caballero
Boy oh boy, what was he thinking? The Chelsea shot-stopper literally gifted the opener to Rebic with an indecision that saw him try to lob the ball over the Croatian forward only to tee him up with an unspectacular chip, and the former had all the space and time to adjust himself before whacking one into the far post for the opener.
Caballero should've done better there, much better, but his nervous touch just set the tone for the rest of the evening. He initially did well to deny Mandzukic from close range in the first-half but wilted when Croatia upped the ante. His howler today was the fourth by a goalkeeper in this World Cup directly leading to a goal, and all this just 5 days after his poor showing in the build-up to Iceland's equalizer.
Caballero was in no man's land when Croatia came for the third, as Kovacic drove him out of his position and fed Rakitic, who had the easiest job in the world of tapping it into the net.
Sergio Romero's injury at the eleventh hour propelled Caballero as the no.1 choice in goal, but Argentina cannot rue the former's absence between the sticks more, after this game.
