Mathieu Debuchy is set to join Bordeaux on loan after Arsenal blocked a potential move to Manchester United, Football Insider sources understand.

United made a bid to sign Debuchy as Louis van Gaal tried to reinforce the decimated full-back position in his squad for the second half of the season.

But Arsene Wenger refused to allow the right-back to join a team he regards as a title rival and the player is now in line to complete a deadline day transfer to Bordeaux.

An Arsenal recruitment source has told Football Insider that the two clubs are hammering out a deal before the transfer window shuts on Monday night.

Bordeaux have confirmed their interest in signing Debuchy on loan for the rest of the season after Arsenal and Aston Villa failed to reach an agreement on a deal for the France international.

“Debuchy will not be joining Aston Villa,” Garde said at his media briefing on Monday afternoon. “Aston Villa wanted a loan. Arsenal wanted a permanent transfer.”

Speaking at his media briefing on Monday morning about whether Debuchy will leave Arsenal in the window, Wenger said: “At the moment it doesn’t look like it, but it’s a possibility,” he said.

But any deal will only be a loan. “It’s impossible to do permanent deal now,” the manager added.

Asked whether Debuchy – who has also attracted interest from Sunderland and Bayer Leverkusen – will be staying in the Premier League, Wenger replied, “yes”.

However, it now appears as if Debuchy is headed back to his homeland as he aims to clinch a place in the France squad for Euro 2016.
