Arsenal have a few selection issues to consider as they welcome Brighton to the Emirates on Sunday.

Sunday’s game is Arsenal’s third in a week and their final game before the October international break.

Despite heavily rotating the squad for Thursday’s win over BATE Borisov, we have a few injury problems and could be end up having to play certain players twice in four days.

Laurent Koscielny is struggling with an ongoing Achilles problem and will have a late test to determine if he can play or not, while Mesut Ozil has yet to overcome an inflamed knee and has been ruled out of the game. With Danny Welbeck already out and Alex Iwobi still a doubt, it leaves us a bit short of attacking options.

Petr Cech, Nacho Monreal, Hector Bellerin, Sead Kolasinac, Granit Xhaka, Aaron Ramsey, Alexis Sanchez and Alexandre Lacazette are expected to return to the starting line-up having been left out of the Europa League game.

Koscielny’s Achilles problem could see either of Per Mertesacker or Rob Holding keep their place in the team. With the German unlikely to play twice in a week, Holding could have another opportunity to impress in the Premier League. Shkodran Mustafi is expected to keep his place as well.

Should Iwobi not make the game, Ramsey could play as one of the two behind the striker as he did against West Brom. However, that would require one of Mohamed Elneny or Jack Wilshere to play in central midfield. Elneny played 90 minutes against West Brom and BATE Borisov, while Wilshere played just his second 90 minutes since returning from injury.

It’s possible that neither will be risked.

That could see Theo Walcott get his first Premier League start of the season. His two goals on Thursday helped Arsenal to a 4-2 win and his workload hasn’t been as high as other players.

Arsenal could line-up like this:

Cech – Holding, Mustafi, Monreal – Bellerin, Xhaka, Ramsey, Kolasinac – Walcott, Alexis – Lacazette
