Chelsea fans have questioned whether Aston Villa's equaliser against them should have stood, due to a foul on Andreas Christensen in the build-up.
The Blues had taken the lead through Olivier Giroud in the first-half, only for Anwar El Ghazi to bag an equaliser just after half-time.
El Ghazi's goal however brought some controversy due to a coming together involving Christensen and Jack Grealish in the build-up.
Grealish was straight back on his feet while the Danish defender stayed down in the rest of the build-up.
