As the Premier League season nears its end, Arsenal manager Arsene Wenger will no doubt be casting one eye toward this summer's transfer window in the search for ways to strengthen his squad; one of these areas, hampered by long-running contract negotiations with current charge Bacary Sagna, will no doubt be full-back.
The most recent report on Sagna's contract, courtesy of the Daily Mail, suggests the Frenchman would demand a deal worth around £20 million to extend his stay at the north London club.
This would, reportedly, include a 50 percent wage increase from £60,000-a-week to £90,000-a-week, on a three-year deal: a demand which would surely jar with Wenger's long-standing age policy, with Sagna currently 31 years old.
Elsewhere, 24-year-old Englishman Kieran Gibbs, whilst performing admirably for portions of the season, can definitely be improved upon: the three-time England international is the club's worst defender in terms of duels won, with Squawka attributing the left-back with a rate of 45 percent.
With one eye on the future, here are five full-backs which Arsenal should look at signing this summer; three right-backs to succeed Sagna and two left-back options to potentially replace Gibbs.
