Barcelona have already spent 160m euros on 10 centre-backs in the past decade
The directors at the Camp Nou have suffered many a headache over the central defensive positons in recent years, with the Catalan club having brought in 10 centre-backs for just over 160 million euros over the past decade.
There have been some success stories at the position, with the signings of Samuel Umtiti, Gerard Pique and Javier Mascherano having worked out very well, even if the latter was technically bought as a defensive midfielder.
There have also, though, been some major busts and a lot of money has gone down the centre-back drain.
The most expensive signings have been those of Umtiti and of Dmytro Chygrynskiy, who cost 25m euros each to arrive from Lyon and Shaktar in 2016 and 2009 respectively.
The next most expensive were Mascherano and Jeremy Mathieu at 20m euros, with the Argentine bought from Liverpool in 2010 and the Frenchman signed from Valencia in 2014.
Both have now left over the past year.
Arsenal have made significant money from the Blaugrana’s centre-back needs too, with Alex Song signed for 19m euros in 2012 and Thomas Vermaelen for 15m euros in 2014.
Of those that remain at the club, Pique is set to stay for some time, while the club are working on renewing Umtiti.
Marlon, meanwhile, has been out on loan this season, at Nice.
