I was always in the camp I have always been firmly in the camp that he should play in defense but I agree with your post. With Terry performing this well, the current squad composition, and having seen his superb performance against Liverpool, I would also play him in midfield. Alongside Ramires with Hazard and Oscar in front of him. It will require a lot of positional discipline from all players but also a great combination of physical strength, players that can do a lot of kilometres and technical ability. I am quite suprised that Lampard is getting that many games of Mourinho. Would really favor Luiz there now that he's back.
