Sturaro is arguably more dispensable, but he is younger and Italian, so we aren't likely to get rid of him. Marchisio, Pjanic, and Khedira are our starters, when fit and in form. That leaves Asamoah and Lemina. Lemina is young and has a lot of potential, is a better tackler, has more pace and an engine on him than Hernanes, and should definitely be kept over him. You might have a case when it comes to Asamoah, but I still hold hope that he might regain 70%-80% of his mobility.
