Arsene Wenger insists Arsenal's confidence has helped his side overcome the psychological struggles from previous seasons after they thrashed Ludogorets 6-0 in the Champions League.
Mesut Ozil stole the show with a second-half hat-trick after Alexis Sanchez and in-form Theo Walcott put Arsenal 2-0 up.
Alex Oxlade-Chamberlain also got on the scoresheet as the Gunners stretched their unbeaten run to 11 games in all competitions, now with seven straight wins.
As one-sided as the scoreline was, Arsenal were put under pressure during the first half and after edging past Swansea last weekend, Wenger believes his current crop of players are better equipped to deal with tricky spells in the Premier League and Champions League than previous years.
