Atletico Madrid 1-0 Arsenal (Agg: 2-1): 5 Talking Points

#3 Koscielny was stretchered off the pitch early on in the game

The Frenchman is likely to be out for sometime.

Just 8 minutes on the clock and Laurent Koscielny went down clutching his right ankle under little pressure from Diego Costa. The look on Antoine Griezmann's face was enough to ascertain the grievous nature of the injury to the Arsenal captain.

The Frenchman is crucial to his national side's chances at the World Cup in Russia and it came as no surprise that the Atletico striker was distraught to see his compatriot in real pain.

A terrible campaign for the centre-back, who is a favourite with the faithful, seems to have taken an even grimmer turn as he left the pitch on a stretcher and appeared to be in agony. A diagnosis confirmed that he has ruptured his Achilles, an injury which has similarly disrupted Santi Cazorla's career at the club.

We can only hope that the Arsenal captain comes back stronger in the days, weeks and months to come..
