Arsenal manager Arsene Wenger has confirmed he's sweating over the fitness of three key players ahead of the game against Liverpool.
"Monreal, Walcott and Oxlade-Chamberlain will be assessed. Koscielny is out," said the Frenchman.
Wenger has also commented on the difference between the Liverpool side of last season and the one of this season, urging his players to be cautious.
"Last year Liverpool scored over 100 goals. Now they're not on the same trend. They came off the blocks very strong last time."
In terms of the threat coming from Liverpool, Wenger earmarked one player in particular his team have to keep an eye on.
"I rate him highly. Everybody spoke about Suarez last year but Sturridge and Sterling were very influential."
Wenger has echoed the comments of some of his Premier League managerial colleagues in suggesting that the Christmas period is a crucial part of the season.
"It's a very important period now. We play four games quickly. How you come out of the Christmas period is very important."
"It's a shock for new players because they're used to a break. Many of them suffer physically."
The Frenchman was asked about Chilean striker Alexis Sanchez, revealing his happiness that the versatile attacker chose to move to North London.
"Every great player has the choice to play where he wants and he chose us. We're very happy."
"I told him the way we play football will suit him and all players want to play in the Champions League."
Wenger also took the opportunity in front of the media to thank club legend Thierry Henry for his time at the Gunners.
"He's had a massive career and I would like to take this opportunity to thank him for what he's done for the club."
"He was a combination of physical talent and intelligence. He was one of the greatest players I've ever seen."
