Webster returning to the left of the centre backs ?
Unfortunately yes. You want your most experienced CB playing in the middle of the back three as he has a huge role in directing the other defenders so its wise to have Dunk or Veltman in that role and I dont want to **** around with the position of White more than has already been done. That leaves BDB or Webster and since Fulham are not much of an aerial threat I'd go for Web.
Of course could also go with White, Veltman, Dunk or similar configuration but as it stands its as much as a risk as a possible gain since Webster got some experience in the role by now.
