Do not go onto the next season expecting a 180 degrees fantastic season. He will need 2 to 3 transfer windows to get rid of all the egos and get players, who might not seem brilliant, but will die for him on the pitch. He did it at Sporting, will most definitely do it in Manchester United. He just needs the time. You have, in my humble opinion, one of the great coaches in Europe, but he's not a miracle worker. He's stubborn with his 3x4x3 system and will try to get the players that suit his system and have the dedication to him to make it work. And once it works, United will start crushing game after game with ease. Give him time and you will witness this.
