Arsene Wenger admitted his relief at coming away with a draw against Spurs, but was left counting the cost of injuries and unavailable players ahead of the league clash against Birmingham on Saturday.
Emmanuel Eboue, Kolo Toure and Alexandre Song are at the African Nations Cup, while Johan Djourou (groin), Philippe Senderos (knee) and Robin van Persie (thigh) will have to be assessed today. Walcott picked up an ankle knock but it is not thought to be serious.
Wenger said: 'We had no injuries before the game but, considering we also have three players at the African Nations Cup, we have lost six players in one night. That is very difficult for us.'
He added: 'It was a good result for us considering Tottenham created more chances than us.
'In two weeks it could change completely and I feel we are in a good position - 2-0 would have killed the game for us.'
Meanwhile, reports in Germany have suggested Arsenal goalkeeper Jens Lehmann has agreed terms with Borussia Dortmund, but Wenger insists a deal has not been struck.
'Lehmann has not gone, he has not agreed personal terms and we have not agreed anything with Dortmund as well,' Wenger said. 'At the moment he is still at the club.
'There is a chance but I believe he has not made up his mind.'
Wenger said that no fee had been agreed with Newcastle for Lassana Diarra but admitted the midfielder may leave.
'It is a possibility but I now have to assess the injuries and see what we can do.'
Elsewhere, Juande Ramos will decide in the next two days whether to restore Paul Robinson to Tottenham's starting XI after dropping the goalkeeper against Arsenal last night.
'We haven't decided yet if he will play on Saturday,' said the Spurs head coach. 'He is a good goalkeeper which he has demonstrated with his career so far, we all know what a good goalkeeper he is.
'There are 24-25 players in the squad and they all have to play at some point and make the most of the minutes they have on the pitch.
'All of the players are important, all are considered and I choose who I think is best for each match. Only 11 can play.'
