Arsenal manager Arsene Wenger has suggested he could still add some fresh faces to his squad but only if he finds quality.
The Frenchman stressed the importance of a strong start to the new campaign before last week's game against West Ham United but his side slipped to a surprising 2-0 home defeat at the Emirates.
As a result, Arsenal fans have asked for the club to sign a world-class striker but the Frenchman says it is not easy to find the right player at the right price in the last few weeks of the transfer window.
"We are as open after that bad result as we were before," Wenger told reporters on Friday morning.
"We were working very hard and we are focused to do what can strengthen our squad. The availability is not big. It is Friday today and we play on Sunday so it is important that we focus on our performance on Sunday.
"When you lose a game you always get that kind of demand [to sign new players], we have to be honest enough and ask, 'Could we have won the game without any addition?' and I would say yes.
"Always the solution comes from outside, lets look inside at ourselves and produce the performance that is expected of us. I think that would be much more intelligent than always expecting a miracle from outside.
"It is exactly the same situation as before the West Ham game. If we find somebody anywhere who strengthens our squad then we will do it. It is not easy, it is not supermarket stuff where you go in and say, 'I would like this, please can you give it to me.' The availability is not easy."
Recent reports have claimed that midfielder Mathieu Flamini will be sold and replaced by Sevilla's Grzegorz Krychowiak.
But the Frenchman rubbished both rumours.
"I expect him [Mathieu Flamini] to be here in September," he said.
"I spoke to him. At the moment he is not involved but he has no intention of leaving. He will be involved at some stage. He works very hard and his intention is to stay.
"[A move for Grzegorz Krychowiak?] No."
