FC Porto hit the crossbar - Gabriel's furious reaction to Saliba spotted

Gabriel was furious with Arsenal teammates for almost gifting FC Porto the lead in Wednesday's Champions League clash. 

Galeno came close to giving the home side after about 20 minutes. William Saliba seemed to stop as the ball looped up in the six-yard box before Galeno nipped in and smashed a shot against the post.

He then somehow puts the rebound wide. Gabriel was not pleased with his defensive partner and showed it immediately.
