Danilo and a now older (soon 32yo, in January) Alex Sandro offer very little going forward, but Danilo is almost playing a MFer position, going central when Casemiro vacates
I would bring on Bruno Guimarães (I rate the hell out him, wanted him since he was at Club Athletico Paranaense, and he is a HUGE reason NUFC are doing so well) for Lucas Paquetá to open up more space and offer more of a passing threat and allow the fullbacks to stay wider, which in term offer their wingers more room
Serbia are absolute giants across the back, so crosses are not truly the way to score IMHO
