Swansea City director John van Zweden feels Manchester City are getting Wilfried Bony on the cheap.
Bony's move to City - for a fee rising to £30 million - was completed yesterday.
"It's about amounts, which do not belong in our league," Van Zweden told De Telegraaf.
"We should be happy that we have seen him here playing for one and a half years. And we have been able to take advantage of all of his goals.
"But if I compare him with other amounts paid, I think it's actually much too little."
