Boss Arsene Wenger has urged Arsenal fans to trust him in the transfer market and insisted they must stop dreaming of an instant solution.
Angry Gunners fans chanted for the manager to sign a striker at the end of their 1-1 draw at Leicester on Sunday.
Olivier Giroud is out until January with a broken tibia and Wenger was linked with Loic Remy before he joined Chelsea on Sunday.
They never pursued a deal for the QPR man, though, despite reports of an inquiry.
Rookie Yaya Sanogo started up front at the King Power Stadium but it was Alexis Sanchez who netted the opener, which was immediately cancelled out by Leonardo Ulloa.
And Wenger wants supporters to remain patient despite Monday's looming transfer deadline.
"As long as the transfer market is open it makes everyone dream by thinking the solution is always somewhere but it's not necessarily obvious," he said.
"The solution every time you don't win is to buy someone. We are out there and we'll try our best and you have to trust us.
"You can't think every time you don't win a game there's a miracle man who can win you the game.
"Why did Manchester City not win against Stoke? They have plenty of strikers, football is a team sport and we cannot sell it too much as an individual sport."
And Wenger, who lost Laurent Koscielny to a head injury, insisted the Gunners will keep looking before the window closes but refused to give assurances on new arrivals.
"I have been in England long enough to know I don't want to promise when I'm not 100 per cent," said Wenger, who also admitted Alex Oxlade-Chamberlain suffered a minor calf injury.
"It is not unlimited money because that's not the way we manage the club. We will try to make the right decision but we have the resources if we think it's the right player."
Ulloa levelled just two minutes after Sanchez's 20th minute opener to claim a deserved point for Leicester.
It was the striker's second goal of the season, although he missed a fine chance in the second half to win the game.
But boss Nigel Pearson believes his side, who have drawn two and lost one in their opening three Barclays Premier League games since promotion, are improving.
"I think when you have a group of players, and a lot haven't experience the Premier League before in this intensity, the three games we have had have been pretty tough," he said.
"They can reflect on the game and know we can get better and improve but they have given as good as they got.
"That should give them confidence.
"There isn't really a great deal of pressure on the players because no-one expected us to beat them. The pressure is on when people make assumptions you should win games. We have to make sure how we judge our players is based on the standards we set ourselves.
"I am pragmatic on how I look at fixtures and reflect on performances."
