Barcelona have already done more transfer business this close season than in most of the last few windows, despite the fact that this particular summer window doesn't actually open until July 1.
The signings of Ivan Rakitic and two high-quality goalkeepers in Marc-Andre ter Stegen and Claudio Bravo has everyone at Camp Nou excited. As does the return of loanees Rafinha Alcantara and Gerard Deulofeu.
Rumours abound of other comings and goings in midfield and up front, but there is still the glaring omission of a quality central defender in the line-up.
It has been five long years since Pep Guardiola signed Dmytro Chygrynskiy for €25 million from Shaktar Donetsk only to send him packing back to the Ukraine at a €10 million loss after one season.
Since then, not one imposing centre-half has been secured. Quite unbelievable given Barca's well-documented struggles with the high ball and at the back generally.
It is imperative that there is a change in buying policy with immediate effect and a defensive rock is next in through the revolving door.
The likes of Porto's Eliaquim Mangala have been taken out of Barca's price range so let's take a look at five realistic targets who could make the switch to Catalonia.
