Tottenham manager Andre Villas-Boas is believed to be interested in raiding Ajax for highly-rated defender Toby Alderweireld.

The north London club have already profited from signing one defender from Ajax, in Jan Vertonghen, and are now seemingly keen to sign his former team-mate.

Like Vertonghen, Alderweireld joined the Dutch side when he was 19-years-old and has become a regular member of the first team, playing more than 100 games for Ajax in all competitions.

He has also played alongside Vertonghen for Belgium in an impressive backline which also features Manchester City captain Vincent Kompany and Arsenal centre-back Thomas Vermaelen.

The Metro has reported that Villas-Boas has been a long term admirer of the 23-year-old, having previously had him scouted on a number of occasions last season when he was at Chelsea.

The Tottenham boss is keen to bring in the versatile defender who has played at right-back for Belgium, but is normally used in the centre of defence by Ajax.

Tottenham do have a number of options at the back, but with Michael Dawson set to quit the club in January, and William Gallas coming towards the end of his career, it seems Villas-Boas feels he still needs further strength in depth.

However, it appears that Spurs will have plenty of competition for Alderweireld as Liverpool and Newcastle are also said to be interested in securing his services.

Alderweireld has certainly had plenty of success with Ajax, winning two league titles, and this season representing the club in the Champions League, which may influence his decision when it comes to possibly leaving.

The Metro believes that the defender would prefer to move to England and that the draw of reuniting with his good friend Vertonghen would be tough to resist.
