However, having watched the development of Mason Greenwood, Marcus Rashford and Anthony Martial since the turn of the year, Neville feels that United's forward players are capable of surpassing those of their rivals.
Speaking to The Gary Neville Podcast, the former defender said: "Mohamed Salah, Roberto Firmino and Sadio Mane are matured, they are established, they are the real deal - the best front three in the Premier League. I was saying that even when Manchester City were winning the league.
"The three that United have got are not at the level of Liverpool's front three yet, you wouldn't expect them to be, but they have the talent and ability.
"There were questions whether Rashford was good enough, whether Martial was good enough and Greenwood hadn't obviously emerged back then, but they are proving they are good enough, that they can play and that they will get better.
"The Liverpool front three are ahead, but it is exciting for Manchester United. If you believe in young players and give them opportunities in the positions they want to play in, you will be amazed what you can achieve."
Greenwood, still three months short of his 19th birthday, netted his fourth goal in three games during Thursday's victory over Aston Villa. body check tags ::
