article: There is a rich and mildly amusing irony about Arsenal fans calling Chelsea boring for defending well, when these Gooners still celebrate a side that ground out results just to preserve their unbeaten record in 2003-04. They drew four of their last seven, the lifeless goalless stalemate at home to Birmingham a particular highlight. Instead of giving a shallow critique fuelled by sour grapes on Chelsea's title winners, maybe those fans should focus on the shortcomings of their own players, and in particular Mesut Ozil. Mesut Ozil has been sublime in recent weeks but he didn't do enough against Chelsea on Sunday . The German, celebrating the FA Cup win over Reading, needs to start performing to live up to his £42m tag . I've enjoyed some of Ozil's recent performances, he's been sublime more than spectacular, but he's definitely been a joy to watch. And so as I sat down to watch Arsenal face Chelsea, I felt confident that Ozil could be the difference between the two teams. I also felt that Arsenal could win the game, and win it well. And that if they did win it well, it would put huge pressure on Chelsea in the run-in. I felt there would be a chance that a big result for Arsenal at the Emirates on Sunday might just open the title door for the Gunners. But it wasn't to be. And come the big moment, the big player fluffed his lines. Ozil wasn't terrible but he didn't impact the game enough. While Cesc Fabregas was sending a killer pass only for Oscar to be wiped out by the goalkeeper (how is that not a penalty?), and Willian carved Arsenal up with the pass of the match to gift a great chance to Ramires,  Ozil was tidy, nothing more. Cesc Fabregas outshone Ozil on Sunday as Chelsea showed why they are ahead of Arsenal this season . Fabregas, who left the Emirates pitch with Ozil's shirt, would have been better than the German for Arsenal . Ozil takes on Cesar Azpilicueta in a game where he was fine, but not good enough to change the result . He didn't stand out. He didn't impact the game enough to affect the result. He didn't show any signs of being world class, or worth £42million. And then when he had the chance to be the match winner, Ozil completely missed his kick with the goal gaping right in front of him. Poor technique. In the second half Chelsea played into Ozil's hands. They effectively gave him the ball and asked him what he could do. If he's as good as he's purported to be, he kills off Chelsea with his ability on the ball. But he couldn't create the winning goal. For all of Arsenal's pivotal, meaningful, must-win games in the last two seasons, Ozil has looked average. Even in the FA Cup final last year it was Santi Cazorla and Aaron Ramsey who stood out, while Ozil failed to shine, complaining afterwards he was tired after his first season in English football. He was the most expensive player on the pitch on Sunday and come the end of his Arsenal career he will be judged on his impact. Ozil could go down the same route as Juan Sebastian Veron (left) and Andriy Shevchenko . When Thierry Henry says Arsenal need a new spine of their team, it's time to start listening . A player with a huge reputation signed for such a huge amount has to be more than just sublime. He has to have a major impact in the big games, he has to take the team to another level. Two seasons have gone and Ozil has failed to do that at Arsenal. There are other big signings with big reputations who have flopped in the Premier League – Andriy Shevchenko, Fernando Torres, Juan Sebastian Veron, and we're still waiting for the biggest of them all – Angel di Maria - to show us what he can do. Ozil could be joining that list unless he delivers something amazing next season. When an Arsenal legend like Thierry Henry points out that after all this time Arsene Wenger has constructed a team without a spine – Henry said they need a goalkeeper, a centre half, a defensive midfielder, and a top striker – you have to listen. He's right of course, but the knock-on effect is that the top players Arsenal have in their team need to deliver something extra special. And Ozil has failed to do that. In one of the biggest games of Arsenal's season, Ozil missed his kick when a late opportunity came his way . Arsenal fans are defensive of the Germany midfielder but that is merely a sign of their low expectations . Henry said what all Arsenal fans know, but most refuse to admit – Fabregas would have had a bigger impact in that team this season than Ozil has. There's a lot of goodwill from Arsenal fans towards  Ozil – they want him to be the hero, they want him to be their superstar. And that desperation means some have over-praised his performances. They're hoping it's some kind of twisted self-fulfilling prophecy – if they keep saying Ozil is brilliant, then maybe he will be. Witness this tweet about Ozil from Arsenal fan @girlgooner two weeks ago: 'I still can't believe he plays for my team Arsenal, I think we are very lucky, he's a very special player.' It seems you only have to sign for Arsenal these days to be a legend. That's how well Wenger has managed and manipulated standards and expectations at this once great football club. As for Ozil, he's been good. But he needs to be brilliant.
