Ajax's Toby Alderweireld has revealed he is open to a move to the Premier League or the Bundesliga, with Bayer Leverkusen ready to rival the English contingent for the defender's signature.

The Belgian international has impressed an array of clubs with his performances at the heart of the Amsterdam club's defence, and it is growing increasingly likely that he will look for a move away from the Eredivisie this summer.

The 24-year-old has indicated that he would be open to following his compatriots Thomas Vermaelen and Jan Vertonghen in leaving Ajax for the Premier League with Liverpool and Tottenham credited with keen interest, although a move to the burgeoning Bundesliga would also be of interest.

"England and Germany are the best leagues where I think I can take the next step," Alderweireld told Dutch newspaper De Telegraaf, as reported by the Independent.

"I have to go somewhere where I can play football a bit and where my style of play suits.

"On the other hand, I do not want to play for a team at the bottom of their league. I want to leave Ajax for a nice club, otherwise I'll just stay in Amsterdam."

Interest from German clubs appears to be solely led by Bayer. While the Bundesliga side have been desperately attempting to address their attacking concerns with forward Andre Schurrle looking likely to join Chelsea this summer, the club have identified Alderweireld as a possible defensive recruit, reports suggest.

Kicker suggest that Leverkusen's sporting director Rudi Voeller was in attendance during Belgium's World Cup qualifier win over Serbia last Friday, alongside the club's sports manager Michael Reschke, and were suitably impressed with his performance.

Should the German club make their interest known, a move to the Bay Arena could be seen as a more attractive proposal than those put forward by Liverpool or Tottenham.

The club earned themselves a spot in next season's Champions League thanks to their third place finish last season. Spurs, who will once again participate in the Europa League next season, and Liverpool, who missed out on Europe altogether, could struggle to tempt the ambitious Alderweireld to these shores, should the Belgian have Champions League football at the top of his agenda.
