Luiz is such a good footballer that you can probably give him a run out in any position and he'll still end up doing good things, but he'll also do bad things. The only reason he's getting praise right now is that his good and bad things are different (not necessarily better) than the alternatives. If we're in a bind and have no one to field in the midfield, by all means give Luiz a run out but to argue that he should be converted to a DM doesn't make sense to me. We should rather just get through this season as best as we can and sign players that can actually play in the pivot, if 4-2-3-1 is the future (I want 4-3-3). At the moment, I'd say we don't have a single player good enough to be first choice pivot player for a team looking to win UCL, EPL. We have players who can do a job depending on the type of game and opponent but not one player who I'd be comfortable being considered first choice regardless of opposition.
