Arsenal captain Robin van Persie says Mikel Arteta has been a "massive" signing this season.
Arteta joined the Gunners from Everton in August.
RVP told the Official Arsenal Matchday Programme: "Mikel Arteta made a real difference in terms of our solidity - he keeps the ball well, knows when to tackle and how to kill a counter-attack, showing his experience and demonstrating that he is a massive player for us."
