Toni is expected to leave Bayern this summer, despite still having a year left on his contract with the Germans.
“We have a keen interest in Toni,” said Preziosi to Gazzetta dello Sport.
“He is a player that has the characteristics of our forwards and we really like him.
“We have made an offer but the problem is that we need to look at the numbers.
“It’s a problem of salaries that are stratospheric. There are things that we cannot afford.
“We will see what he decides.
“But I insist that we cannot go crazy, we will go up to a certain amount.”
