Arsenal boss Arsene Wenger admits visa problems may delay Park Chu-young from making his debut.
Wenger confirmed the relevant paperwork had not yet been completed, but remained optimistic it would be in time for the striker to feature tomorrow.
Speaking to a pre-match news conference, the Arsenal manager said: "We have an uncertainty still with the visa of Park.
"He is in Paris at the moment, but we hope it will be sorted out tonight.
"He has been away playing against Lebanon and Kuwait. From Kuwait he has flown directly to Paris and should come back tonight."
