Arsenal manager Arsene Wenger is facing a selection headache after it was revealed that Danny Welbeck is a doubt for the Gunners New Year's Day clash with Southampton.
The summer signing from Manchester United played 85 minutes and scored in Sunday’s 2-1 victory over West Ham United, but looks likely to miss out on the game at St Mary's on Thursday with a thigh injury.
"We have one alert after the game at West Ham and that's Danny Welbeck," the Frenchman said.
"He could be short for Thursday [He has] a thigh problem."
The former Monaco coach also confirmed that Theo Walcott is fit to face the side he left as a 17-year-old following three consecutive appearances as an unused substitute since returning from injury.

With Olivier Giroud suspended for the second of three games, the Gunners boss faces the dilemma of facing the Premier League's second meanest defence without either of his first choice forwards, meaning Walcott could make his first start for the club since January 2014.
Other options include Bordeaux bound Yaya Sanogo, Joel Campbell, and wantaway World Cup winner Lukas Podolski.
