Toby.
He's been at fault for as many goals as Jan or Dav has.
It's just his errors have been less glaring. When Dav or Jan fuck up, they do it in style.
Alderweireld was at fault for the goals against Burnley? I've got Foyth marking Woods from a corner as Pochs error and a combination of Aurier, Sissoko, Eriksen and Vertonghen for their winner.
The Chelsea opener was poor from Alderweireld but not necessarily an individual error. I'd put it down to him being on his unnatural side which is to supposedly help out Sanchez. That goal stemmed from Eriksen though once again.
Theyve all been poor though, I will agree on that.
