Leeds United left-back Laurens De Bock is undergoing a medical at Greek club Aris Thessaloniki as he completes a loan-to-buy move today, Football Insider understands.

United have all but agreed the terms of the deal in which the defender, 26, will join on a season-long loan with a view to a permanent transfer of £500,000.

A Leeds source has told Football Insider that the paperwork on the deal is being finalised today as Aris heads to Greece to put pen to paper. although it is not yet complete.

Football Insider revealed last month that De Bock had told his agent to find him a new club after accepting he had no future at Elland Road.

He spent last season on loan at Belgian top-flight club K.V. Oostende after he was frozen out of the United side at the start of the campaign.

Marcelo Bielsa has made it clear there is no way back into the senior set-up for De Bock, who struggled to fit in at Elland Road after joining from Club Brugge for a fee of around £1.5million in January of last year.

Leeds are set to lose £1million on the player, if he makes enough appearances this season to trigger his loan being converted into a permanent transfer to Aris.

The Greek club finished fifth in last season’s top division and secured a place in the Europa League second qualifying round.

At Leeds, De Bock is behind not only senior pair Barry Douglas and Ezgjan Alioski in the left-back pecking order at Leeds but also rising star Leif Davis and the versatile Stuart Dallas.

In other Leeds United news, Marcelo Bielsa is freezing out senior outfield international and wants him gone in the next 24 hours.
