Whilst sitting in a 'comfortable' fourth place in the Barclays Premier League, title hopes seem questionable for the Gunners as the campaign reaches its climax. 

By the time the Gunners kick off against Tottenham Hospur at White Hart Lane tomorrow, Wengers men could be 10 points behind Chelsea, albeit with 2 games in hand. 

With Chelsea, Liverpool and Tottenham all to play, the next few weeks will be crucial for all the top flight teams in the battle for the silverware. 

Arsenal centre-back, Per Mertesacker has warned that Arsenal have cannot afford anymore slip ups and there is simply no room for error. 

"These are all decisive games," Mertesacker told Sky Sports' Weekend Warm-Up.

"There are no points to drop anymore. They are vital games and we are up for it.

"We have to concentrate on ourselves and we have to stay as close as possible to the top and that is the most important thing to us."

"It depends entirely on our finish; how we cope with the situation of our injured players and the situation that we have another chance in the FA Cup."

Despite Mertesacker's vow of confidence in his club, Arsene Wenger seems concerned by multiple injuries throughout the squad.

As mentioned, this stage of the league is crucial and every player is essential to ensure success as they head into the crux of the season. 

With key players, such as Mesut Ozil, Jack Wilshire, Aaron Ramsey and Theo Walcott all out due to injury, the next few fixtures will be tough.

Wenger told the Guardian: "I am concerned that this happens. If you look at our overall injury list going into such a decisive part of the season, we have no Wilshere, Ozil, Ramsey and we went to Bayern without Gibbs and Monreal. "It's very difficult to find an obvious reason why."

"We are analysing very deeply why it happened and to see if there is a link between all these injuries.

"For Walcott it's completely bad luck. Wilshere - I don't think it is linked with the other injuries, it's more linked with his history and the kick he got. But the rest, maybe we have to find why it happened."

In a more positive light, this could bring in Kim Kallstrom, a very talented Swedish midfielder into the squad for his debut against Spurs, following a back injury.
