Arsenal face a big test of their Premier League title credentials on Sunday when they make the short trip to arch-rivals Tottenham.
Mikel Arteta's Gunners, seeking their first league title since 2004, start the weekend five points clear of second-placed Manchester City.
Fifth-played Spurs are vying to win four consecutive home league matches against Arsenal for the first time.
"I think the players are in a good emotional state," said Arteta.
"They are excited, they are enjoying playing together and obviously we are in a good position. We have to now improve a lot of things and maintain a lot of the good things that have taken us this far.
