Arsenal's hopes of Champions League qualification hang by a thread, and the Gunners cannot realistically afford to drop any more points with four Premier League games remaining.
The same goes for Jose Mourinho's Spurs, which makes the result of today's derby so vital to both teams.
With so much potentially riding on one game, Arteta's squad looked to be enjoying themselves in the sunshine on Saturday as the likes of Pierre-Emerick Aubameyang, Hector Bellerin and Alexandre Lacazette put in some last-minute preparations before their short trip to Tottenham Hotspur Stadium today.
Mesut Ozil (back) is likely to miss out again, while Pablo Mari (ankle), Bernd Leno, Gabriel Martinelli and Calum Chambers (all knee) are definite absentees.
Provisional Arsenal squad: Martinez, Macey, Bellerin, Soares, Sokratis, Luiz, Holding, Mustafi, Kolasinac, Tierney, Xhaka, Guendouzi, Torreira, Ceballos, Maitland-Niles, Willock, Ozil, Nelson, Pepe, Aubameyang, Lacazette.
