Arsenal have slight doubts over midfielder Freddie Ljungberg (knee) and centre-back Johan Djourou (foot) ahead of tomorrow night's Champions League Group G clash against Porto at the Emirates Stadium.

Manager Arsene Wenger said this afternoon: "We will see how Freddie is tomorrow as he has not practised today.

"Djourou as well, but they should both be available."

Captain Thierry Henry is expected to start again having shrugged off his recent foot problem.

Wenger added: "Thierry is match fit. He has had a game after an injury and so should be sharper tomorrow."

Philippe Senderos (shoulder), Gael Clichy (foot), Lauren (knee) and Abou Diaby (ankle) are all still a few weeks away from a return.

Provisional squad:Lehmann, Eboue, Toure, Hoyte, Djourou, Gallas, Hleb, Baptista, Fabregas, Gilberto, Rosicky, Van Persie, Flamini, Adebayor, Almunia, Ljungberg, Walcott, Song, Henry.
