As has been painfully clear in the Premier League and Champions League this season, Arsenal need new defenders.
Laurent Koscielny and Sebastian Squillaci haven't lived up to expectations so far, while it remains to be seen whether Thomas Vermaelen will fully return to the form before his achilles injury.
As for the full-backs, on the left Gael Clichy's future is up in the air, whilst Kieran Gibbs isn't showing true defensive promise. And on the right, Bacary Sagna is getting all too comfortable with no challenge for his position.
And of course, it's clear the Gunners need experienced, world-class players who can lead the team and make a strong defensive impact at the Emirates, giving Arsenal the winning mentality and steel edge they so desperately need.
Therefore, new recruitments across the back four seem likely to be Arsene Wenger's transfer priority in the summer window, with a marquee defensive signing a decent possibility.
Here are eight experienced, world-class defenders Wenger and the Arsenal board of directors should consider this summer.
