Portugal Colonial - Arteta grapples with defensive injury crisis ahead of Monaco clash

The Gunners are seventh in the new-look Champions League format after three wins in five matches -- one place above the Ligue 1 team.

But Arteta, whose men are also third in the Premier League, is juggling a lengthy injury list.

Gabriel Magalhaes and Riccardo Calafiori, who both missed Sunday's draw at Fulham, were absent from Tuesday's training session, along with Oleksandr Zinchenko, Jurrien Timber and Thomas Partey.

Right-backs Ben White and Takehiro Tomiyasu are still absent with knee injuries.

"We have to manage a lot of the players, so they're probably not going to be fit for tomorrow and are a doubt," Arteta said at his pre-match press conference on Tuesday.

"I still have 24 hours to make those decisions and hopefully the right ones.... In the ideal scenario, we have to be in charge to make those decisions because it's forcing us to make it for the wrong reasons, but as well, we need to accept the reality and move forwards."

Arsenal stumbled at the start of last month but won four straight games in all competitions before Sunday's 1-1 draw.

But the Spaniard said he was happy with how his men were coping in the absence of a settled back line.

"The good news is that the team still reacts and plays in the way that we want and becomes so dominant, and we want to do that regardless of who plays and I think that belief is within the team and it's really positive," he said.

Arteta said there was an opportunity for defender Kieran Tierney to return -- the 27-year-old Scotland international has yet to feature this season.

"He is ready and he's training really well and he's going to have an opportunity for sure with the way the team is looking at the moment," he said.

"It's for that reason and because he's earned it as well with the way he's behaved and the way he's been with us."
