Benitez wants to see the Magpies show some vision and ambition in the summer window as he bids to end years of fighting relegation on Tyneside.
He told Marca: "The owner (Mike Ashley) knows it: me and my team are looking for a future project, competitive and ambitious.
"Let's see if we are in the same line.
"It does not depend on what I believe.
"I stayed in Newcastle and it was a high risk.
"We could not save them the first year, we missed a couple of games, but the next we went up.
"It is a top club and to stay was a sign that we are professional coaches.
"We are in it to win titles, avoid a descent or whatever.
"Then the idea was to invest to enter the top 10, but the money did not reach the expected level.
"Now we are once again solving a problem of that lack of investment."
