Mathieu at CB has been a total nightmare. Mathieu at LB has historically been even worse. Fun fact, Deportivo is the game Mathieu single handedly costed us last season, also playing from LB, and that was when he was younger and still had his meniscus.
Mascherano has been having terrible games week in, week out as well. I want to give Lucho the benefit of the doubt and say he's only playing because Umtiti is just returning from injury... but somehow I doubt it.
And Digne at RB? I dunno, man.
And Rafinha at RW is fine and all but if Paco is really so useless to even Lucho that he can't get a start here then I have to seriously question why he was bought in the first place.
If we drop points it's all on Lucho.
