Steve McClaren has made a statement that there's still a few signings to go and are far bigger and more surprising than Mitrovic, Gino or Mbemba
I think that's a massive hint at Charlie Austin or Saido Berahino but he also went on to say a few of these signings have been kept massively under wraps and will only be revealed once it's clear they can't be hijacked.. See Loic Remy.
Mbemba to be confirmed tomorrow anyway.
