Spanish giants Barcelona and Real Madrid are both reportedly interested in Ajax’s Belgian defender Jan Vertonghen. Vertonghen, 22, is a regular at the heart of Ajax’s defence and has ensured that the Amsterdam outfit do not feel the absence of Thomas Vermaelen, who moved to Arsenal last year.

Vertonghen had spells with VK Tielrode and Geerminal Beerschot in his native Belgium before joining Ajax as a 16 year old in 2003. He was sent out on loan to RKC Waalwijk to garner valuable first team experience in 2006. He was a rare starter in the 2007-08 season but made his mark the following season after the departure of Johnny Heitinga.

Vertonghen is currently contracted to Ajax till June 2013. A versatile player, Vertonghen plays in midfield while donning the colours of the Belgian national team.

Real are also tracking the progress of Vertonghen’s team mate Christian Eriksen. The Danish youngster is widely hailed as one of the future stars of the Eredivisie. He made his senior debut last month against NAC Breda and has also attracted the attention of Manchester United, Chelsea and Arsenal.

Eriksen’s contract with Ajax is due to expire next summer but the club are working towards giving him a new deal. Head coach Martin Jol has already expressed his desire to keep Eriksen at the Amsterdam Arena for as long as possible.

Eriksen joined Ajax from OB in 2008 for a reported €1m fee. The 18 year old has already represented Denmark at U-17, U-18 and U-19 levels.
