Arsenal are in a state of crisis heading into the new Premier League season - what's new?
With Per Mertesacker out for at least four months and Gabriel Paulista suffering an untimely - and serious - injury against Manchester City on Sunday night, the Gunners will be extremely light at the back when they face Liverpool on August 14.
As a result, Arsene Wenger now has no choice but to make defensive reinforcements.

A new centre-back is needed most at the Emirates Stadium, with Valencia's Shkodran Mustafi linked with a £25 million move despite having a £42 million release clause.
However, reports from Germany suggest that whilst Wenger is keen on a new centre-half, it's a right-back that's on his radar.

According to Bild, the Frenchman is "hot" on 20-year-old RB Leipzig defender Lukas Klostermann.
Contact has been made between the two clubs, with Arsenal making clear to "the environment of Klostermann" that they're interested.
Cue groans from the club's impatient fans.
Klostermann - a right-back by trade - is versatile and can play anywhere across the back line, but another young defender is far from what Arsenal need.
The Gunners are desperate for greater experience at the back considering they already have the likes of Hector Bellerin (21), Calum Chambers (21) and Rob Holding (20) in their ranks.
Mustafi represents the perfect summer signing having won the World Cup with Germany and played Champions League football for Valencia.
His intelligence and tough-tackling approach would complement Laurent Koscielny's all-action style of play.
Following Gabriel's injury, Wenger confirmed he is on the lookout for defensive additions but insisted he will weigh up his options upon learning the Brazilian's fate.
"I’ve said many times that we are in the market," he told Arsenal's official website.
"Of course it’s not an easy market for us. Let’s hope we have good news from Gabriel.
"Laurent Koscielny is back in training [on Monday] but he might be short for next week [Premier League opener against Liverpool].
"If Gabriel is out, Per Mertesacker is out and Koscielny not ready - that’s a lot of players."
On the injury itself, Wenger added: "We have not even made a diagnosis in the medical room with our doctors or physios yet. I can’t tell you more.
"He's in pain. Let’s hope the pain is not a sign of bad news. The only thing we have to know now is how big the damage is with his ligament."
