Whether through restrictions by the board or through his own stubbornness, Arsene Wenger has failed to fully strengthen Arsenal in the last few seasons.
He did address one area of weakness during the January window, with the transfer of Malaga left-back Nacho Monreal.
Central midfield, central defense and the forward positions could also use strengthening if the Gunners really want to challenge for silverware next season.
There's certainly no shortage of transfer rumours involving the club.
Arsenal have been linked (per Talksport) with Fiorentina forward Stevan Jovetic. Powerful French midfielder Etienne Capoue is also being lined up as a potential signing (via the Telegraph).
According to the Daily Mail, Swansea defender Ashley Williams is a target for the Gunners, and they may face competition from Liverpool for his signature.
Whether these exact players arrive or not, the Gunners do need to change some personnel during the summer.
Arsenal does have a solid mixture of veterans and youth, but with some players constantly under-performing it's time for a change.
