But Mourinho doesn't, not only because the squad would lose the ability to control possession, but mainly because we'd be out of bench options to change the game attackingly. No one would be afraid if we subbed Lingard or Mata in, would they? Come Ibrahimović, that's another matter completely.
I take the points about the bench and the tactical element to not starting Martial and Rashford together, even though I think they'd be fine operating in tandem from either side.
However I don't see Zlatan's addition to the squad as an issue either way. Lukaku is the top striker at the club now and Zlatan won't be taking minutes off our wide forwards.
