West Ham sit second bottom of the table with just two wins from their opening 15 games, their worst ever start to a Premier League season.
With only 10 points, David Moyes faces a huge task to keep the Hammers in the top flight after losing three and drawing one of his opening four games since replacing Slaven Bilic.
Things don't get any easier either with the daunting prospect of Chelsea and Arsenal up next.
West Ham had the fifth worst defence last season but neglected to improve it this season with only the ageing Pablo Zabaleta added on to the back line.
The Argentine has struggled in most games, looking completely exposed in a back four.
When the Hammers operate a back five Zabaleta looks a lot more comfortable but with Sam Byram out injured long term Moyes has a lack of cover for a player who turns 33 next month and it shows.
Debuchy was on the verge of leaving the Gunners in the summer but a last minute move to France collapsed and The Sun claims he will be one of four players allowed to leave in the January window.
West Ham have been linked with Jack Wilshere and Theo Walcott in previous windows but their biggest concern is stopping goals going in at the other end.
Debuchy has been an outcast for the last two years and would relish the chance to revitalise his career without any upheaval by moving across London.
