Chelsea have completed the signing of Dutch international defender Khalid Boulahrouz from Hamburg for an undisclosed fee.
Chelsea are thought to have paid in the region of £6m for the 24-year-old who passed a medical and agreed personal terms at the weekend.
“In a short squad and in a country where you can have only 16 players for a match, it’s important to have cover for many positions,” said Chelsea boss Jose Mourinho.
“So now I can have Boulahrouz, Ricardo Carvalho and John Terry – three options for the centre. I can have Paulo Ferreira and Boulahrouz – two options for the right side; I can have Boulahrouz and Wayne Bridge – two options for the left side.”
He spent two seasons at Hamburg and made his international debut in September 2004.
Boulahrouz started the last two World Cup games for Holland at the World Cup but he was red-carded in their controversial defeat by Portugal in the last 16.
“He is a good competitive player and will be a good addition to our squad,” Chelsea’s assistant manager Steve Clarke told Chelsea TV.
“It is important to have one or two players around the squad who can play in a number of different positions.”
