Yeah it was but that's the thing, he probably expected Eder to Dribble so he backed off.
either way not his fault his team mates decided to go missing.
That was not Umtitis fault. Koscielny missed the marking, got dribbled past and left Umtiti alone.
Umtiti did mostly right in that situation, you cant bullrush becouse then you get easily dribbled past.
All he could do was to try and cut of an angle, which he did.
Umtiti was second best in France after Sissoko, excellet positioning, good tackles and great forward passes.
