Arsenal boss Arsene Wenger has revealed he has considered moves for David Villa and Marouane Chamakh.
Wenger insists he has money to spend to strengthen his squad, but that he has not been able to push through the right deal.
A new striker has been mentioned as Wenger's top target during this month's transfer window following the injury to Robin van Persie, but so far the Frenchman has yet to bring in a new forward.
Wenger has admitted he looked into the possibility of signing Bordeaux's Marouane Chamakh and Valencia's David Villa, but that neither club were willing to do business for the players.
"It is not only about wanting to buy, it is to find better players than what you have available and we haven't until now. It is as simple as that," Wenger told the club's official website.
"You always want to add a [Cristiano] Ronaldo if you can, but is he available and where is he?
"Marouane Chamakh is not available because he is playing with Bordeaux and Bordeaux don't want to release him. David Villa as well, Valencia don't want to let him go."
Wenger also believes he has enough strength in his squad to cope without bringing in any new faces
"I believe as well the extra push can come within the club and the easy solution is always to look outside," added Wenger.
"When you look deeply at what is happening to us, we have the best attack in the league; we scored more goals than anybody else. That means at least if you can do that for the first 20 or 21 games, why not in the other 18?"
