I agree with this completely. I think Benat would be a smart buy price-wise that would offer us the deep playmaking we could really use. But he's only 5'8" (1.75m) or so, which is kinda small considering the size of the rest of our team. I suppose we could play him most of the time, and then swap him for Luiz or Lamps against more physical sides. Benat, Lampard, Luiz, and Ramires would give us a ton of different strategic options. His height leads into the next question though: if he's too small, who, aside from Fellaini, is big enough, good enough, cheap enough, and available instead?
