Arsenal fans will never forget the sense of euphoria they felt when Mesut Ozil arrived from Real Madrid in 2013.On September 2, the Gunners announced the statement signing of Ozil in a £42.4 million deal from Los Blancos.The two signings that preceded Ozil were rather underwhelming, the relatively unknown Yaya Sanogo joining from Auxere and Mathieu Flamini returning following a five-year stint at AC Milan.So to see Ozil, a world-class player who would go on to win the World Cup with Germany, at the Emirates Stadium was certainly a high for the club and their supporters.“I am thrilled to be joining a club of the stature of Arsenal and am looking forward to playing in the Premier League,” Ozil, 24 at the time, told the Gunners’ website.

“It will be great for my own personal development as a player and I am particularly looking forward to working with Arsene Wenger.

“From our negotiations it is clear the club has huge ambition and I look forward to being part of an exciting future.”

What Wenger said after Ozil signed

Wenger was just as delighted after signing a proven winner.

“I have said throughout the summer that we have been working hard to bring in top quality players to this football club,” the Frenchman said.

“Mesut is a top quality footballer who will be a fantastic addition to our talented squad.”

Yet four years on and Ozil and Arsenal are preparing to break up.

It was reported by the Mirror last night that the German has told his Arsenal teammates that he wants to sign for Manchester United, who have been linked with the playmaker for some weeks now.

Ozil’s contract expires at the end of the season and he’s shown no desire of extending it.

And so the Red Devils could try their luck with a cut-price offer in January, or wait until the summer to land Ozil on a free.

What Man United fans said on Twitter

Man United fans are excited at the chance to sign a player who has been an assist-king in his four seasons in England, but what were they saying when Arsenal signed him in 2013?

Some Man United supporters weren’t entirely fussed, claiming Shinji Kagawa was more than good enough as a playmaker.

Some preferred Kagawa

Many were upset with Arsenal getting a star

Others were gutted at missing out on the player, who was 24-years-old at the time he arrived in north London.

'A poor man's Cleverly'

Meanwhile, there was one who even had the cheek to call Ozil a “poor man’s Tom Cleverly". We presume he was joking…

Ozil v Fellaini

Plenty compared Ozil’s move to Arsenal against Marouane Fellaini’s to Man United, which was completed on September 3.

Pretty interesting stuff. It'll be worth following the reaction of Arsenal fans if Ozil ends up at Old Trafford.
