Arsenal supporters have taken to social media to react to the starting line-up that head coach Mikel Arteta has picked to face Sheffield United.
The Gunners go into the game 10th in the Premier League table, with one win and one defeat in their last five league games.
A disappointing draw against Crystal Palace last time out was compounded by a red card for Pierre-Emerick Aubameyang - meaning the striker is suspended for this afternoon's clash and the two games afterwards.
They face a Sheffield United side flying high in sixth place, though there have been two defeats in their last three league games.
Some supporters took to social media to express their thoughts on the line-up, with many concerned by the changes to the back four, and the presence of Shkodran Mustafi - who has not played much Premier League football this season.
Elsewhere in the team, Arteta has recalled the fit-again Gabriel Martinelli to replace Aubameyang, while Alexandre Lacazette, Mesut Ozil and Nicolas Pepe start again.
Granit Xhaka and Lucas Torreira anchor midfield, while Bukayo Saka fills in at left-back with Sead Kolasinac injured.
At the back, Sokratis misses out with illness, with Mustafi coming in to partner David Luiz.
