Arsenal are back in action on Wednesday night as they look to make it back-to-back Premier League wins against London rivals Chelsea.
The Gunners recovered from their Europa League disaster against Villarreal with a won over West Brom last time out, sending the Baggies down to the Championship.
But as they look to make it consecutive wins, they face a very stern challenge with a trip to Stamford Bridge to face a Chelsea side in fine form, now looking set to finish inside the top four with Champions League and FA Cup finals to play.
The Gunners will, however, be helped by a triple injury boosts ahead of the clash with Thomas Tuchel 's men.
David Luiz looks set to remain out with the club saying ahead of last weekend's West Brom clash: "David has made very good progress since sustaining the injury at Newcastle last Sunday. David will continue his rehabilitation over the next week."
But Emile Smith Rowe will likely play despite limping off after feeling a tweak in his hamstring last time out.
Both Pablo Mari and Granit Xhaka are also likely to return after respective injuries, giving Aerteta three boosts ahead of this one.
And with those updates in mind, here is the full squad available to Mikel Arteta, including the three boosts.
Goalkeepers - Bernd Leno, Mat Ryan, Alex Runarsson.
Defenders - Hector Bellerin, Kieran Tierney, Rob Holding, Calum Chambers, Gabriel Magalhaes, Cedric Soares, Pablo Mari, Joel Lopez.
Midfielders - Mohamed Elneny, Emile Smith Rowe, Granit Xhaka, Bukayo Saka, Thomas Partey, Martin Odegaard, Dani Ceballos.
Forwards - Alexandre Lacazette, Pierre-Emerick Aubameyang, Nicolas Pepe, Eddie Nketiah, Gabriel Martinelli, Willian, Folarin Balogun, Reiss Nelson.
