Mikel Arteta has demanded 'explanations' from Premier League referees after Gabriel Martinelli's controversial red card for Arsenal against Wolves on Thursday night.
The decision, which occurred in the 69th minute at the Molineux, set the Gunners back but they were ultimately able to show the resilience needed for a top-four spot by grinding out a big three points with a 1-0 win against the West Midlands outfit.
However, on another day, a decision like that could cost the north Londoners vital points, with Gabriel Magalhaes an example of this when he got sent off in the 2-1 Man City loss.
