Arsenal manager Mikel Arteta failed to rule Gabriel Martinelli out of their Champions League clash on Tuesday.
The Gunners are set to face a do or die game against FC Porto in the last 16 of the knockout phase.
As they are 1-0 down after the first leg, the Gunners do need a win, but Martinelli may miss the game due to a bad cut.
"Not many updates," Artetea said in his pregame press conference on Monday.
"We still have 24 hours and we're trying to have everybody fit and available."
On the availability of Martinelli, he then added: "Percentage you want? There are options. Sorry to disappoint you."
