Arsenal midfielder Mikel Arteta will be out of action for "approximately three weeks" with a calf injury, manager Arsene Wenger has confirmed.
Arteta missed Sunday's clash with Manchester City with the injury, the first league action he has missed this season.
Wenger revealed that the Spaniard would be undertaking a scan on Monday.
When asked would Wenger dip into the transfer market to replace him, he said: "To find a player of his calibre in January? I wish you good luck."
I WON'T PULL OUT OF TACKLES - KOMPANY
Manchester City captain Vincent Kompany tonight vowed to not change his approach to tackling after his red card in the 2-0 win at Arsenal.
The Belgian was sent off by Mike Dean for a challenge on Jack Wilshere, with the official interpreting Kompany's 75th-minute tackle as a two-footed one.
Kompany disagreed, posting a picture on his Twitter account which appeared to show his left foot being in contact with the pitch as he went to make the tackle.

He did write that he did not blame Dean, however, saying: "First. Massive congrats to our team and fans, great game! Also. No grudges against the referee, I understand the difficulty of the job."
His manager, Roberto Mancini, stated his intention to appeal the decision, a move which could see a three-match ban extended to a four-game one, and Kompany admitted that may not work, while also defending his style.
"About the tackle: If the ball is overrun by the opponent and a 50/50 challenge occurs, collision is inevitable," he said, tagging on his picture.
"Ultimately I'm a defender: Appeal may work or not. I will never pull out of a challenge, as much as I will never intend to injury a player."
