The Brazilian expressed his frustrations after the Gunners dropped another two points in the Premier League against an old enemy
David Luiz has urged Arsenal's defenders to "take responsibility" for their mistakes after a 2-2 draw with Tottenham at the Emirates Stadium on Sunday.
The Gunners followed up a 3-1 defeat against Liverpool at Anfield last week with another sub-par defensive display against Spurs.
The visitors raced into a 2-0 first-half lead thanks to a Christian Eriksen tap-in and a Harry Kane penalty, before Alexandre Lacazette halved the deficit with a well-taken goal just before the interval.
