5 Instances when Diego Costa could have been punished against Arsenal

#2 Chest-bump on Koscielny

Costa Barges into Koscielny sending him to the ground

Immediately after the first incident, Koscielny and Costa clashed again, this was the direct catalyst for a string of events to unfold. The Spanish striker went to ground in a tussle with the Arsenal man and when he rose from the ground, it was with such vehemence that a chest bump from him sent Koscielny crashing to the ground.

While the defender may have exaggerated the impact, it was surely a reaction that could have evoked a caution at least from referee Mike Dean. However, things for the next few minutes would escalate so fast it became a blur and you can’t fault the referee for not doing much about it.
