Mikel Arteta has been one of the most important players for Arsenal this season. He has operated as the deepest-lying midfielder, linking the play between defence and attack. He has played 33 out of Arsenal's 37 Premier League matches, playing 2956 minutes (second highest, after Santi Cazorla, out of all Arsenal players). He played 90 minutes in every game that he has started except against Spurs (he was technically substituted after 90 minutes against Wigan).
As everybody knows, the match against Newcastle on Sunday is enormously important. Wenger was frustrated that Arteta was injured and said in a pre-match interview, "For the weekend, we have the uncertainty over Mikel Arteta, who had to come off
just before the end of the Wigan game with a calf strain. Honestly, his chances
of being available are minimal. I have to be realistic and prepare for another
solution."
