Yeah, I don't think there's going to be room for a destroyer-type in front of three centre-backs.
The recent games where combinations of Delph, Allan and Iwobi dropped into a back-seven (United and Chelsea at home) were understandable given the circumstances, but you can't set up to invite pressure like that every week and get away with it.
If the plan is to replicate what Thelwell presumably oversaw at Wolves, the lack of anyone similar to Neves or even an old-as-dirt Moutinho must be something that Lampard is concerned about.
