Liverpool’s Philippe Coutinho looked so scared when Arsenal’s Bacary Sagna barked in his face [GIF]

It was triggered by an injury to Kieran Gibbs.

With 15 minutes to go during Arsenal’s 2-0 win over Liverpool, the Gunners left-back Kieran Gibbs picked up a calf injury which could keep the Englishman out of the match with Borussia Dortmund in the Champions League this week.

With Gibbs needing of medical attention, Liverpool carried on playing, and that caused Gunners right back Bacary Sagna to flip.

Pissed at Philippe Coutinho’s failure to initially kick the ball into touch when Gibbs was hurt, the French full-back aggressively barked in the young Brazilian’s face, and the Liverpool #10 was quick to back off.

With Coutinho looking a little bit scared from Bacary’s bark, it was left to Luis Suarez to step in and make sure tensions didn’t boil over.
