With just 18 months remaining on his current Arsenal deal, Alexis Sanchez's problematic contract situation will be starting to worry Arsene Wenger.
The Frenchman has made it very clear that he wants his Chilean star to extend his stay but, for one reason or another, he's yet to put pen to paper.
Fans and the media alike have speculated what the problem is, with many pointing towards Arsenal's lack of silverware as the issue.

However, according to the Mirror's chief football writer John Cross, that's far from the case.
Speaking on Sky Sports' Sunday Supplement, Cross insisted Sanchez is happy in north London but documented the two factors preventing him from signing a new deal.

"Of the two players Arsenal are trying to negotiate with at the moment - [Mesut] Ozil and Sanchez - Ozil is much more likely to sign," he said.
"I think Ozil will sign, but Sanchez is a bit more problematic. He has just 18 months left now. He is a very good player, he had a very good first season and was not so good last season - it was disrupted by injury.
"And I still think it's a little bit up in the air over whether he will sign. I think there is some doubt over whether Sanchez stays or goes.
"He's on £130,000-a-week at the moment and wants in excess of £200,000-a-week, and also in the mix I understand he wants some sort of buy-out clause, which would give him the ability to get away if the right move comes along.
"Ozil is stealing the limelight and I think he will definitely get in excess of £200,000-a-week. Whether Sanchez does too, we will see.
"Ozil already earns slightly more than Sanchez, which is an unusual situation because normally the superstar striker is the biggest earner at the club.
"Sanchez is happy in London as I understand it, but I think he is a little bit more restless than Ozil. I'm not saying he's desperate to get away, but Arsenal have more of a battle on their hands to keep Sanchez."
So, let's recap. According to Cross, Sanchez's contract talks have stalled for two reasons: he wants a buy-out clause inserted into any deal and to be joint-top earner with Ozil.
If you were Wenger, wouldn't you just say yes to the Chilean's demands? This is a world-class forward we're talking about after all.
The buy-out clause shouldn't worry fans - it's little more than a safety net - and it's completely understandable for Sanchez to want more money as one of Arsenal's best players.
