Defensive Output
This is one of the key areas in terms of evaluating the performances of the two players considering the roles that they play for Arsenal, and Flamini outperforms Arteta in this regard quite comprehensively.
Arteta has managed 40 interceptions, 2 blocks and 40 clearances in his 21 appearances, or simply put, he performs a defensive action every 19.3 minutes on the pitch. Compared to that, Flamini has managed 29 interceptions, 9 blocks and 45 clearances in his 19 appearances, i.e. he performs a defensive action every 13.9 minutes on the pitch.
While Arteta has been a part of more duels, his overall success rate is much lower than that of Flamini. Arteta has won 44% of 112 attempted tackles and 44% of 55 headed duels. Flamini on the other hand has won 46% of his 46 attempted tackles and 65% of his 26 headed duels. Flamini (2) has also committed less defensive errors than Arteta (4).
Other Factors
In terms of discipline, Arteta and Flamini have both been sent off once- Arteta was sent off against Crystal Palace in October while Flamini was sent off against Southampton in January. However, Arteta (2) has collected less yellow cards than Flamini (4).
Arteta has scored two goals, both from the penalty spot- one against Crystal Palace in the 2-0 win and the other in the 5-1 thrashing at Liverpool- while Flamini has scored a solitary goal which came from open play in the 3-0 win against Cardiff.
The Verdict
The roles the two players play, although comparable, are not the same. So pitting them directly against one another seems unfair to the both of them as both bring their unique skillsets to the table. However, based on the numbers, Flamini seems to have outperformed Arteta so far this season.
