Leeds United have made a late ambush to beat West Ham to the signing of teenage defender Matthew Bondswell, Football Insider has learned.

The Hammers are confident of completing the capture of the left-back, 18, from RB Leipzig after, as revealed by this site, he headed to England on Monday for a medical and to finalise personal terms.

A West Ham source has told Football Insider that Leeds have made last-gasp advances for Bondswell in a bid to lure him to Elland Road.

But the high-flying east Londoners are confident of finalising a deal for Bondswell, who has been capped by England at Under-18 level.

Intriguingly, Leeds also failed with a late move for another young defender – Frederik Alves – before the 21-year-old Dane joined West Ham at the end of last month.

West Ham are confident Leeds and the other main interested parties will not derail the Bondswell transfer, which could be completed this week.

Chelsea have also had a longstanding interest in the left-sided defender, while Sporting Lisbon have also been in contact over a potential deal.

It is regarded as a major coup for the Londoners, given the senior experience accumulated already by Bondswell.

The Nottingham Forest academy product joined RB Leipzig two years ago as he joined the rush of British talent heading to Germany to fast-track their careers.

He has made seven appearances this season while on loan at Dutch club FC Dordrecht, six of which have come as a starter in league matches.

But that season-long switch is now set to be terminated as he closes in on a permanent move to West Ham.

In other news, Danny Mills has claimed West Ham will “finish in the top six” if they seal their new top target by next week.
