In signing Özil, Arsenal did not only sign a world-class player, but a midfielder who would improve morale. This signalled intent, and everyone - players, fans, board members - knew it.

Arsenal's performances this season speak for themselves. Top of the league after 16 games and through to the last 16 of the Champions League, where they will face Bayern Munich in a rematch from last season. They are playing with class (as usual), but also efficiency. Beating Borussia Dortmund at the Signal Iduna Park is no mean feat; just ask teams like Malaga - who lost 3-2, but were 2-1 ahead in the 90th minute - and Real Madrid, who slumped away with a 4-1 loss.

"Wengerball" is working once again. The excitement has returned to their style of play and it is becoming almost unstoppable. Opponents are on the back foot as Arsenal press forward, attempting to play their game in the opposition half. The short passes are still the main feature, as the North London side play short passes an average of 505 times per game. These quick, infiltrating passes have worked wonders for Arsenal, tiring defenders and allowing them to create chances.

The revelation for this season has to be Welsh midfielder Aaron Ramsey. Although Ramsey has been good since the beginning of 2013, he is directly influencing results by adding goals to his game, with ten so far this season and seven assists. Top goalscorer so far this season for the Gunners, Ramsey has been key. His link-up play with the likes of Jack Wilshere, Mathieu Flamini and Mesut Özil is marvellous to look.

Another player whose performances have been top-notch is Per Mertesacker. Rival fans often talk about the German's lack of pace; and while this might be true, it is only on a very rare occasion that this is exposed. This is down to his positioning, enabling him to make well-timed interceptions - averaging 1.8 per game - and time his movements to clear the ball perfectly, with an average of 5.1 clearances per game. Add to this the fact that Mertesacker is almost unbeatable in the air and you'll see why strikers struggle to get past him.

Every side has a weakness though. Laurent Koscielny, although he has the makings of a great centre-back, suffers from the occasional lapse in concentration. For club and country this season, Koscielny has conceded three penalties, and been sent off twice. Up until this season, first-choice 'keeper Wojciech Szczesny was considered to be unreliable but, in fairness, the Pole has turned his performances around, with 11 clean sheets in 22 appearances.

The quality throughout the side is simple to see. Six different players have won Man of the Match awards so far this season, Ramsey having won the most, with five.

Arsenal could very well go all the way this season. After 8 years without a trophy, the Gunners look dominant in the Premier League this season and, even in the Champions League, they could go far. Playing like one of the best teams in the competition, even with the likes of Bayern and Barcelona, all it would take is maintaining the level of performance and maybe a bit of luck. We've seen luck before, with Chelsea's Champions League win in 2012 - the footballing gods were definitely on their side, and United in 2008 - John Terry's slip was incredibly fortunate for the Manchester club. What is to say that Arsenal can't do the same? In this form, anything is possible.
