Mesut Ozil has proved to be one Arsenal's best signings in recent years, since his £42.5 million arrival from Real Madrid in 2013.
And the midfielder, alongside fellow high-profile singing Alexis Sanchez and manager Arsene Wenger, is currently negotiating a new deal at the Emirates.
The Germany international has been an instrumental part of Wenger's team and scored a Champions League hat-trick in midweek, to help the Gunners beat Ludogorets 6-0.

However, there have been growing concerns that Arsenal's two FA Cup victories, since his arrival at the club, may not be enough to tempt the 28-year-old - in the prime of his career - to remain in north London.
But summer signing Lucas Perez, who arrived from La Liga during the summer, believes that Ozil will not be making a move in the opposite direction, having spent three years in the Spanish capital.

Reports have recently surfaced that the German would 'jump' at the chance to return to the Santiago Bernabeu, with it believed he feels he has 'unfinished business' with Los Blancos.
However Perez, as per The Sun, said: "No, I don't think Ozil wants to return to Spain.
"You never know. Real Madrid is a big club - but so is Arsenal."
Gunners on song
The Gunners are currently joint top of the Premier League, with only goal difference keeping them behind early pace setters Manchester City.
But Arsenal are famed for their mid-season flops and falling short of the league title over the past decade, meaning keeping their star players may become a more difficult task, with Sanchez also in his prime.
"We are always in touch and that's our desire." Perez added.
"Mesut Ozil is 28 years old. He is in the prime of his career. We want him to contribute to the success of the club in the future.
Gunners the right place
"They want to be happy. They are happy at the club and I want them to commit to the club because I believe they are in the right place."
It's no wonder that Perez wants the Germany midfielder to commit to the club, considering the difference he could make in a potential title challenge, and clearly Perez sees signs that the club can end the 12-year absence of the Premier League title in north London.
But until Ozil - who has netted three league goals so far this campaign - officially commits to a new deal, which is set to see the midfielder handed a significantly increased wage package, Arsenal fans are going to remain on edge about the German's future at the Emirates.
