In Alex Song, Arsenal has one of the best defensive midfielders in the league after Yaya Toure and Scott Parker.
Song routinely breaks offences up and provides great cover for the back four. His runs are also exquisite, and he can pick up the occasional assist.
Mikel Arteta has been a quality signing—his crossing is impeccable, and he holds onto the ball beautifully. His set pieces are sublime. His maturity and experience along with that of Mertesacker, have been invaluable as well.
Aaron Ramsey, despite being a bit wasteful at times, is quickly establishing himself as a great midfielder. His passing is precise, as is his dribbling. His concentration does leave something to be desired and he is not a strong aerial player or clinical finisher, but his midfield play is superb.
Alex-Oxlade Chamberlain has been a revelation, as we have witnessed in the handful of games he has played. Against AC Milan, during the second leg, he was the main reason Arsenal were almost able to turn the humongous deficit around.
Players like Yossi Benayoun and Tomas Rosicky also provide options for rotational policies, and Benayoun and Rosicky have been known to deliver on a consistent basis.
Arsenal also has Jack Wilshere who will be fit for next season.
Wilshere proved what a massive talent he really is when he was Arsenal’s player of the season, the PFA young player of the season, and PFA team of the year.
The roster continues to get better when you factor in both Gervinho and Theo Walcott. Gervinho cuts inside in a remarkable fashion, and his dribbling skills and passes are impressive.
Although Walcott can leave you frustrated on many occasions, he has had a splendid season thus far. He is just 22 years old.
Above all, Arsenal has the hottest striker in World Football today in Dutchman, Robin van Persie.
The lack of quality substitutes remains an issue for the Arsenal camp. Recently, it was the substitutes, or lack thereof, which cost Arsenal a quarterfinal berth in the Champions League. Running out of resources, Marouane Chamakh and Park Chu Young had to be called upon.
