Injured Bendtner ruled out for a month
Arsene Wenger revealed Nicklas Bendtner will be out for a month after Arsenal's FA Cup third-round win over arch-rivals Tottenham.

The Denmark striker suffered an ankle injury when scoring the opening goal in the 2-0 Premier League victory over Cardiff City on New Year’s Day.
Bendtner was sent for a scan and Wenger revealed on Saturday after the 2-0 victory over Tottenham that the 25-year-old will be sidelined for around four weeks, leaving the Premier League leaders short of options in attack.
Theo Walcott was employed in his preferred position as a striker against Tottenham, but the England international was carried off with a knee injury late on.
The former Southampton man did not appear to be in pain as he gestured to Tottenham fans to remind them of the score when he was carried off.
Wenger will wait to discover the extent of Walcott's injury and revealed the away supporters had pelted his player with coins.
He said: "Theo has a knee problem, we don't know if it is a stretched ligament or just a kick.
"I've seen the pictures (of Walcott's gesture) afterwards. It does not even look aggressive, it's smiley. The doctors said to me the coins were raining over his head and that is why."
