Disclaimer right away: This article is by no means a criticism of Javier Mascherano. He is a living legend at the club and one of my favorite players ever. The six years he’s been a member of the team have been fruitful – 18 trophies – and he’s been a great contributor to winning. He’s not afraid to get down and dirty defensively and has brought grit to our back line. But he’s essentially been playing out of position for six years. Which is why it’s not blasphemy, in my opinion, to suggest he ought to be replaced by Samuel Umtiti.
