(Reuters) - Arsenal's Champions League group stage win this week was a confidence boost ahead of Sunday's game against rivals Tottenham Hotspur but the team does not need any extra motivation before a north London derby, manager Mikel Arteta said.
Arsenal have started the season in fine style, earning 13 points from five Premier League games so far, and enjoyed a triumphant return to the Champions League on Wednesday with a 4-0 hammering of PSV Eindhoven.
