A striker. But really, one thing that is overlooked in football is cohesion, which takes months and months if not years to achieve. When you bundle a load of new players together, it takes time. Successful teams tend to have a core of players that have played together a long time, and each season 2 or 3 are added. Newcastle takeover was far more effective than Chelsea, they looked at their squad and asked what was the priority to improve and gradually improved it bit by bit. Arsenal the same too since Arteta took over. Chelsea will improve, but they need time and stop being silly in the transfer window, although they definitely need a striker
