LONDON: Liverpool reached an agreement on Tuesday to sell Xabi Alonso to big-spending Real Madrid, subject to the Spanish international midfielder passing a medical.

Liverpool, which finished second in the Premier League last season, said the terms of the deal will remain confidential and undisclosed.

However, Spanish media reported that Real agreed a fee of euro30 million ($43.2 million) for the 27-year-old Alonso, who will be given a four-year contract according to the Web site of El Mundo newspaper. The paper added that he would earn euro4.5 million a year and that his signing closes Madrid's summer buying spree.

The move would take Real's recent spending to more than $300 million, with the club having already brought in the likes of Portugal winger Cristiano Ronaldo from Manchester United, Brazil playmaker Kaka from AC Milan and France striker Karim Benzema from Lyon.

The spree since Florentino Perez regained the Spanish club's presidency in June is designed to take Real back to the top of the game after its bitter rival Barcelona won the Spanish league and cup double, along with the Champions League, last season.

Alonso, who joined the Reds in 2004 from Real Sociedad and helped the English club win the Champions League in 2005, has been a regular under Liverpool's Spanish manager Rafa Benitez.

At international level, he also helped Spain become European champion in 2008.
