Arsenal were beaten 4-1 by Chelsea in the Europa League final in Baku on Wednesday night.
That is likely to impact Arsenal's transfer plans with Emery given a budget of just £40m with more funds only provided through player sales.
Asked if the defeat will affect his targets, the Arsenal boss said: "Maybe, but I think we are a big team and I think Arsenal are a big name in the football world.
"A lot of players want to play here. I don’t know for the next year but the club is working and we will do our way."
He added: "It is not the moment to speak about that. We need to analyse, speak to the players and the club.
"Our idea is to carry on with the same team and improve, and maybe some players need to leave to take a new way.
"We need the same idea and maybe add some new players to give us a situation to improve.
"I am proud of our work, I think the players did all they can in the possibility to reach our target."
On the defeat, Emery added: "We knew it was going to be difficult to get our first target. In the Premier League we were closer to achieve that.
"The other way was the Europa League, we tried and worked. Congratulations to Chelsea, they were better than us."
