Francis Coquelin has been ruled out for three months in a devastating blow to Arsenal’s title chances.
And, as such, the Gunners’ squad suddenly appears vulnerable and precarious ahead of the forthcoming festive schedule.
Here are five midfielders Arsene Wenger could look to sign in January in order to ensure Coquelin’s injury does not scupper their season.

Every time the transfer window opens the rumours of Victor Wanyama joining Arsenal seem to do the rounds on social media.
But this time the Gunners have a genuine reason to sign him, with the former Celtic midfielder once again in a fine vein of form.
His physical prowess makes him one of the strongest midfielders in the top flight, and would add the strength that has long been missing since the days of Gilberto Silva and Patrick Vieira.
Whether or not Ronald Koeman would be likely to sell him midway through the season remains to be seen, but the Saints would no doubt cash in should they receive a substantial offer.
It seems hard to believe that William Carvalho is still only 23.
The Portuguese starlet seems to have been around for ages but, despite attracting a lot of interest from the world’s top clubs, is still at Sporting Lisbon.
Carvalho was one of the standout performers at the U-21 European Championships in the summer, and is reportedly stalling on a new contract with his current club.
If he does opt to leave the capital then he would fetch a large transfer fee, which Wenger could pay in order to help his side maintain their title charge.
After seven years in Belgium with Anderlecht, Lucas Biglia was granted his big move to Lazio in 2013.
And, nearly three years on, the Argentinean has established himself as one of the most consistent performers in Serie A.
The Italian side finished third last year but have endured a difficult start to the current campaign, languishing in eighth place.
Such a start could see their star midfielder leave, yet prising him away from the Italian capital could present an expensive problem.
Two years ago Luiz Gustavo seemed destined to swap the Allianz Arena with Bayern Munich for the Emirates Stadium with Arsenal.
However the 28-year-old decided to remain in the Bundesliga with Wolfsburg instead, where he won the Deutscher Pokal last term.
Now it seems he could finally move to England to plug the gap left by Coquelin’s injury.
The German side sanctioned Kevin De Bruyne’s move to Manchester City in the summer and may have to do the same again with their bulldozing midfielder.
Like Gustavo and Wanyama, Christoph Kramer is another who is linked with the Gunners during every single transfer window.
Another to ply his trade over in his homeland of Germany, the youngster was part of the squad that won the World Cup in Brazil last year.
Since then he has developed impressively and is now the heart of Bayer Leverkusen’s midfield.
With the German side battling to qualify for the Champions league however, a move in the summer appears more likely.
