Arsenal manager Mikel Arteta says his side are taking on a Paris St-Germain team at the “highest level”.
The Gunners face the French champions on Tuesday evening after drawing their Champions League opener away to Atalanta a fortnight ago.
PSG beat Spanish side Girona 1-0 in their first match and have reached the semi-final stage of Europe’s premier competition in three of the past five seasons.
“The opposition we are facing tomorrow is probably the highest level you can find in European football,” said Arteta, who played for PSG between 2001 and 2002.
“But it is a great opportunity for us to see how we deal with it and how prepared we are and how we can impose ourselves in this kind of context.”
Arteta also said defenders Ben White and Riccardo Calafiori will be in contention for selection.
White has missed the Gunners’ past two matches with a knee injury, while Calafiori landed awkwardly on his left leg in the closing stages of his side’s win over Leicester on Saturday.
“Obviously he [Calafiori] was a bit emotional after the game,” added Arteta on Monday. “Let’s see how he is today.”
