AZ Alkmaar have agreed to sign Willem II defenders Joris Mathijsen and Kew Jaliens and midfielder Tarik Sektioui from the end of the season.
The trio all join on on free transfers.
“This is a welcome reinforcement,” said the club’s technical director Martin Van Geel.
“With these signings we will try to realise our ambition, to create a steady position at the top of the league and try to qualify for Europe.”
