Manchester City's two-year European ban was overturned by the Court of Arbitration for Sport on Monday, which means only the top four teams will qualify for next season's Champions League.
Asked if the top-four was vital to his summer transfer deals, Lampard said: "Not really a question just for me and it is a hypothetical one for me to answer before the event, hence why I don't jump forward into that.
"We have brought a couple of players into the club already, which shows positivity about where we want to go.
"We know the club not being able to do business in the last two windows has meant we haven't been able to bring in, move players out and I think that is as an important thing than bringing players in at times, to keep freshening up the squad and keeping the competitive nature of it.
"I know where I want to go with the squad, but that has to be a fluid conversation with the club. Of course, economics will come into it, so we will cross that bridge when it comes."
