You are very right. Since Ferguson's retirement at Manchester United the team has not been the same. Beyond his strategies Ferguson was a leader for the players. His cunning was not only on the court but in the dressing room.
But the equipment must be renewed in order to innovate. Manchester United must find a better striker and a midfield that supports and distributes the ball.
Regarding Liverpool, he must take advantage of his advantage and continue to score goals and points.
