Both Arsenal’s main centre-backs are out ahead of our tie with Liverpool at the Emirates.
Per Mertesacker has been struck down in the prime of life with illness, while Laurent Koscielny is suffering from a mild back problem.
In their place is Gabriel, who we’ve seen little of since he joined, but has delivered when asked, and young Calum Chambers, who primarily plays at right-back but has voiced his desire to move centrally.
It’s a big game to be starting a new back four but it can’t be helped.
