Arsenal midfielder Mikel Arteta has praised the improvement shown by his team-mates since their north London derby defeat at White Hart Lane last month.
The Gunners have won four games in a row since Gareth Bale and Aaron Lennon condemned them to defeat, and Arteta, who has acted as captain for Arsene Wenger's side in the absence of Thomas Vermaelen, has pinpointed an improved level of communication on the field as a key factor in their impressive run of form.
The Spaniard told Arsenal's official site: "We have improved our communication since the Bayern game, but there is still further room to improve too.
"You talk whenever you think it is necessary. There's no point just talking for the sake of talking - you only open your mouth to say something important or relevant. If not, it is better to keep your mouth shut!
"Communication can help the team to unlock its potential, it's one of the things that can be improved. From the things we can do as a group, I think this is one of the important factors."
Arteta highlighted the vocal nature of Arsenal's magnificent 2-0 win in the Allianz Arena as the blueprint for their subsequent performances, with Wenger's men having conceded just two goals since making significant changes to his back-four and goalkeeper.
Vermaelen is expected to come back into the defence at the expense of the suspended Per Mertesacker this weekend as they play host to relegation candidates Norwich City.
Another victory for the Gunners will keep their momentum going in their bid to play Champions League football next season.
