The Premier League side can secure a place in the last-16 with a Group F victory over their French visitors, whom they beat 1-0 thanks to a last-gasp winner by Aaron Ramsey in Marseille two weeks ago.
"They will both be available and in the squad tomorrow," Wenger told a news conference on Monday referring to Vermaelen and Jenkinson, who came on as substitutes in the 88th and 75th minutes respectively on Saturday.
"Are they fit enough to play? Yes, of course."
Arsenal's leaky defence played a large part in a poor start to the league season and matters have not been helped by injuries to the likes of Vermaelen and right back Bacary Sagna who broke his leg this month.
"He is an exceptional player, who takes advantage as well of the fact that we are a very offensive team, that the whole team works very hard for him," the Frenchman said.
