Ajax have signed defensive midfielder Demy de Zeeuw from Eredivisie champions AZ Alkmaar subject to a medical after the two clubs agreed an undisclosed fee.

The 26-year-old began his senior career with the Go Ahead Eagles before joining AZ in 2005 for a fee of 100,000 euros.

De Zeeuw made his debut for Holland in a Euro 2008 qualifier against Slovenia in March 2007 and has gone on to win 20 caps for his country.

AZ confirmed the transfer, with a brief statement on their website, www.ajax.nl, saying: "Ajax have met our asking price."

Ajax will present their new signing at half-time of their meeting with Atletico Madrid in the Amsterdam Tournament tonight.
