AC Milan vice-president Adriano Galliani says their deal for Oguchi Onyewu ends their plans for defensive signings this summer.
Galliani said: "With Onyewu our defence has been completed. There is no need for [Aly] Cissokho or anybody else.
"We had been following him for some time and he replaces [Philippe] Senderos. We have no doubts over Alessandro Nesta, while Thiago Silva is the replacement for Paolo Maldini.
"There is no point suggesting other names, from Philippe Mexes to Andre Santos."
