As expected, AZ Alkmaar have completed a double swoop on Willem II for Moussa Dembele and Kemy Agustien.
AZ coach Louis van Gaal has had his eyes trained on the pair for some time and finally wrapped up the deals on Thursday.
Striker Dembele (pictured) has signed a four-year deal, while midfield star Agustien has been handed a five-year commitment.
AZ technical director Marcel Brands believes the pair can help the club challenge for the title next term.
"We are very proud that Moussa has chosen us," Brands told the club's website. "The competition was fierce.
"There were teams nationally and internationally who were interested and it is good for the future that he comes to play in Alkmaar.
"With Kemy we again have succeeded in contracting a big Dutch talent and that fits well in the future vision of AZ.
"We expect that both players can become of big value for the club."
AZ keeper Theo Zwarthoed could be heading for a loan stint away from Alkmaar.
"We are looking for a second keeper behind Henk Timmer," said AZ press officer Erik van Leeuwen. "We want to keep Theo, but want to loan him out.
"We are talking with, among others, Excelsior."
