Atletico Madrid had right-back Sime Vrsaljko and manager Diego Simeone sent off inside 13 minutes in the Champions League semi-final first leg at the Emirates.
Croatian international Vrsaljko was shown red after picking up two bookings in ten minutes, in what was the fifth quickest red card in the history of the Europa League.
He was shown yellow just two minutes in, before a late challenge on Alexandre Lacazette resulted in him being shown his marching orders.
The 26-year old was furious but replies showed his dismissal was probably justified.

Then the craziness continued as manager Simeone was sent to the stands for trying to get Arsenal right-back Hector Bellerin in the book.
Arsenal fans took great pleasure in waving the Argentine off.
Here's how Twitter reacted:
It's a pity Diego Costa was named as a substitute or else he might have got involved!
