Mikel Arteta confirmed that both Gabriel and Declan Rice are both doubts for Arsenal's Premier League clash at Nottingham Forest on Tuesday night.
The pair were forced off in the Gunners' 5-0 win over Crystal Palace two weekends ago and Arteta will undoubtedly have an eye on Sunday's clash with Premier League leaders Liverpool.
However, the club's dip pre-Palace triumph means every encounter is crucial, and we should expect both Gabriel and Rice to start if they're fit. Thomas Partey, however, will not make the matchday squad despite returning to training last week.
Predicted Arsenal lineup vs Nottingham Forest
Here's how Arsenal could line up at Forest on Tuesday night.
Goalkeepers & Defenders
David Raya (GK) - Off the back of his best performance in an Arsenal shirt, Raya will not be relinquishing his spot between the sticks on Tuesday.
Ben White (RB) - White was back to somewhat near his best last time out, and the boss will hope the Englishman can sustain that level the rest of the way this term.
William Saliba (CB) - I don't think Chris Wood will be testing Saliba in behind, although Forest's spritely playmakers will give the Frenchman something to think about.
Gabriel (CB) - Gabriel set the Gunners on their way against Palace, but he's a doubt for this one with a knock. I suspect he'll be fine to start.
Oleksandr Zinchenko (LB) - Zinchenko may not be enjoying the best of seasons, but there's a notable drop-off when Jakub Kiwior deputises for the Ukrainian.
Declan Rice (DM) - Rice has not picked up a major hamstring injury, although the boss did confirm that there are doubts over his status for Tuesday. Despite Liverpool coming to town on Sunday, I think Rice will start at the City Ground with Thomas Partey out.
Martin Odegaard (CM) - There are no doubts over the skipper's spot in the side in midweek.
Kai Havertz (CM) - I like Havertz in games like these. Arsenal will require his physicality, capacity to win duels, and threat from set pieces.
Bukayo Saka (RW) - I think we're all waiting for Saka's season to ignite. The winger's been productive this term but is yet to dominate. Perhaps he'll produce another killer moment on Tuesday.
Gabriel Jesus (ST) - The Brazilian is without a goal since 17 December, but there's no doubt that Jesus is Arteta's best #9 option. The club will not be signing a striker before the January deadline.
Gabriel Martinelli (LW) - Leandro Trossard scored on his return to the team last time out, but Arteta won't hesitate to return to the Brazilian at the City Ground after his brace off the bench.
