Boasting a two-goal advantage at the interval against last-place Watford on Sunday, Arsenal emerged for the second stanza to record an insipid performance in a 2-2 draw.
The single point flatters the Gunners who appeared as clueless as their manager Unai Emery, a tactician whose stubbornness and repeated tactical miscues cost Arsenal. Sunday's stalemate at Vicarage Road shone a spotlight on Emery's porous midfield set-up, calamitous backline, and overall lack of gusto.
Here's a look at eight stats that reflect how worryingly poor Arsenal have been under the Spaniard:
2 - David Luiz has been at fault for two penalties in four league matches this season after conceding just three in 160 league outings with Chelsea.
4 - Arsenal have been outshot in four of their five league fixtures this season with 31 fewer efforts than their opponents over that stretch.
10 - The Gunners' 10 goals conceded from the penalty spot since the start of last season is joint-worst with Brighton in the Premier League.
14 - The 14 errors by Arsenal leading to opposition goals since the start of last season are the most in England's top flight.
25 - Considering both individual errors that led to a goal and penalties scored by opposition since the start of last season, Arsenal lead the league on 25 goals allowed. Bournemouth are second with 16.
31 - Watford's 31 attempts were the most they've registered in the Premier League, and the most Arsenal have conceded in the top flight since Opta began collecting such stats.
59 - Under Emery, Arsenal have conceded 59 goals in 43 league matches.
96 - Arsenal have faced 96 shots this season in five league outings, more than any other side in Europe's top five leagues.
