      Arsenal playmaker Mesut Ozil has stated hanging up his boots from the task of defending the country. He is reluctant to defend the German national team because they feel the victims of discrimination.

Arsenal recruit Ozil from Real Madrid for 42.5 million pounds. Ozil was able to show his best game during the Gunners uniform.

However, it is undeniable that Ozil also often makes Arsenal fans feel very frustrated. He is considered a lazy player and is often seen disappearing in big games.

Although Ozil is Arsenal's main star and has signed a new five-year deal, this may be the right time to sell the player.

Here are three reasons Arsenal should sell Mesut Ozil as reported by Sportskeeda:

•• New Coach Philosophy

    For starters, Unai Emery's game style centers on enthusiasm, tight pressing, and energy with and without balls.

So far, Emery has been talking about building a team around Aaron Ramsey and Aubameyang. Emery just mentioned a bit about Ozil even though she got the No. 1 jersey. 10 at Arsenal after Wilshere left the club.

Ozil's game style does not fully match Emery's style so it remains to be seen whether he can change his game to fit the scheme or Emery will make changes to accommodate the German player.

•• Performance Drop

     Ozil will be 30 years old on October 15 this year. Although the game is not based on speed or strength, many may wonder how the game has gone down over the last few seasons.

In the Premier League, in the 2015/16 season he scored 6 goals and 19 assists, in the 2016/17 season he scored 8 goals and 9 assists and in the 2017-18 season, he scored only 4 goals and 8 assists. Furthermore, in the Europa League, he scored only 1 goal in 7 matches.

Ozil is seen disappearing for a long time and can not show his contribution when his team is in dire need. Ozil's appearance clearly decreased.

If he does not fit into the philosophy of the club and the new manager is not very interested in him, Arsenal have to sell it so as to reduce his salary burden. Ozil's sales money can then be used by Emery to bring in more effective players.

•• Self Confidence Declines

   Every coach who worked with Ozil always described him as a "confident player". He is portrayed as a player who can not perform if he is not comfortable with his surroundings and has the full support of everyone around him.

After announcing his retirement from the international scene, he does not look calm and it has been visible since the World Cup yesterday. Therefore, it will be difficult to predict its appearance in the 2018-19 season.

Unai Emery must be under pressure to deliver maximum results and sub-standard performance will keep Ozil over on the bench, further reducing his confidence. If Ozil does not play well this season, the price will decline in the future.
