Arsenal manager Arsene Wenger believes that his side's clash with Tottenham Hotspur on Saturday will be important in deciding which club finish in the top four.
The Gunners are currently a point and a place behind behind their North London rivals in eighth in the Premier League.
"The results in the derbies can have a big influence on the Champions League qualifying spot," BBC Sport quotes Wenger as saying.
"They are always a team who are fighting with us now and what's important in the end is consistency."
Arsenal finished third in the Premier League last season, while Tottenham finished fourth.
