Arsenal boss Mikel Arteta is seeking major cash backing for the summer market.
The Gunners resume their top-flight campaign at Manchester City on Wednesday night languishing in ninth place in the table, eight points behind Chelsea in fourth.
Asked if Chelsea's move for RB Leipzig striker Timo Werner makes him concerned over Arsenal's ability to spend money in the market, Arteta replied: "Well let's see, we're trying to put a plan together to improve what we have.
"The fact we haven't got into Europe [the Champions League] has put enormous pressure on the club in financial terms.
"We know what our responsibility is at the end and how much that will relax the financial position that we're in, but we have to go game by game.
"We know the target and we know the difficulty of it it because there are a lot of clubs involved in the fight. But we have to give it a go and believe that we can do it.
"We haven't been able to achieve the goals we want in the last three years. There's a reason behind it and if we stand still, obviously, that gap will be getting bigger and I haven't come here to accept or do that."
