Arsenal are challenging for the title this season and one of the main reasons for their current reign of success is their consistency at the back.
That consistency comes from a settled back four - a settled back four that is under almost immediate danger of being disbanded.
Bacary Sagna is the right-back of this impressive defensive quartet - but his current deal expires in the summer.
Contract talks are said to be hanging by a thread - as the French international wants a longer contract than what is being offered by the Gunners.
With apparent interest from France, Italy and Turkey it appears that Arsenal may have to soon begin a search for new full-backs to take his place in the starting line-up.
One player that has been mentioned in the past is the right-back reportedly destined to become a French regular at the position. Sebastien Corchia has been a long-term target for the club - according to sources in France.
A former French under-21 international - he has been linked with The Gunners for over a year now as he seeks a move from struggling outfit Sochaux.
However that deal seems to be off the cards.
Corchia was unveiled as a Lille player last week - after the teams agreed on a €2 million fee for his services.
Game over, right? Wrong!
Corchia’s deal has not been ratified and is on the verge of collapse after it emerged the 23-year-old’s switch had not yet been verified by the National Directorate of Management Control (DNCG).
They monitor and oversee the accounts of all the professional clubs in France - and have ruled that Lille have ‘insufficient bank guarantees or excessive payroll’ in order for such a move to be signed off by the organisation.
Lille have confirmed an appeal, and hope to have him available before their next fixture.
But this is a serious delay, and if a deal was to collapse it may play right into the hands of Arsenal - who could get a second swipe at the full-back said destined to captain France one day.
