Arsenal boss Unai Emery insists he took plenty of positives from his team's display in the 3-2 defeat to Chelsea on Saturday.
The Gunners are without a point after two matches having lost 2-0 at home to Manchester City, 8/13 to win the Premier League title once again this season, last weekend.
Arsenal fell 2-0 behind in the first quarter of the match at Stamford Bridge with Pedro and Alvaro Morata scoring for Chelsea, but they were level at half time thanks to two goals in four minutes by Henrikh Mkhitaryan and Alex Iwobi.
After a tighter second half, Marcos Alonso scored Chelsea's winner, and Arsenal are now 13/5 to finish in the top four of the Premier League this season.
Former Valencia and Paris St-Germain boss Emery said after his side's London derby defeat: "First, it's whether you win or lose. We lost. The result is important.
"We want to win. This is always the way but it is clear that defensively we suffered three goals but also we had chances to score more goals. I think the result is 3-2 but we also think we did [have] chances to score more.
"But it is one process. In the second half we played with two midfielders who were 19 and 21 years old. They improve and are continuing. I am happy without the result."
