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

Manager Arsene Wenger said: "We will see how Freddie is on Tuesday as he has not practised on Monday. Djourou as well, but they should both be available."

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