The Football Association hopes video evidence will prove to FIFA that Dele Alli's obscene gesture was aimed at England team-mate Kyle Walker rather than any official or opponent.
Moving to within touching distance of the World Cup finals last week was overshadowed by the fallout to the Tottenham attacking midfielder's middle-finger gesture in the 2-1 qualifying win against Slovakia.
Annoyed not to win a free kick after a collision with Martin Skrtel on the edge of the box, TV footage showed Alli swearing when play was halted -- something he was quick to point out on social media was aimed at Walker.
