Pavard seems a little bit more versatile than Sule from what I've seen, so I'm guessing it'll be Pavard at LCB along side Sule at RCB. I wonder if Boateng or Hummels will be shown the door.
I believe back in mid-December United triggered the one-year extension in Martial's contract, so it now runs until 2020. They may have to sell him though if he won't sign a new contract by the end of the season.
