Left back, right back and right wing.
We desperately need to inject some pace into the side. If we're to alter our game, we need to utilise overlapping fullbacks to open up opportunities to cross a ball. If we do that, DCL and Broja become more useful. Even if we bring in a left winger and allow Ndiaye into the middle, or allow Lindstrom in there (I feel he has more to show). I don't think we need wholesale changes, but a few well placed changes (alongside a managerial change) COULD change our fortunes.
