Son is fresh back from an injury and Kane has been appalling for a while now. Kane isn't even trying by what people say. They may once have been one of the most lethal combos but only Son is lethal at this point.
I'm not for one second defending Nuno, but this club is a magnet for off-field issues that cause big problems on it. The Rose interview, the Kane Interview, Poch's book, the Amazon Documentary, Eriksen's contract fiasco, all of Mourinho's very public mismanagement of players, the 3 month search for a manager, the Super League, Harry's court case and now this mess of an international break.
Why do you think Nuno was in such a bad mood during and after the international break?! He knew that the momentum he had managed to build in a very limited time was obliterated by off-the-field issues.
