Neville feels Louis van Gaal's Red Devils outfit is decent but suggests that they are a couple of key players away from seriously challenging for the premiership.
The Sky Sports pundit said on the 'Gary Neville Podcast' that perhaps United need to go after such players as Real Madrid duo Cristiano Ronaldo or Gareth Bale, or even Barcelona aces Neymar and his Suarez, in order to mount a real title pursuit.
"But they need that match-winner, that Neymar, that Luis Suarez, the one that is going to light up a game and score one or two goals to take it away, then all of a sudden they would look like a Barcelona, because they're dominating possession, making teams look foolish.
"Even in the last 15 minutes (against Leicester at the weekend), they didn't fully commit to winning the game.
"Historically, you would like to see punch after punch, you would want to see bodies being thrown forward, but you might get caught on the counter attack and lose 2-1 that way.
"But that's not the way in which this Manchester United team play, and the heart wants them to go forward, commit players and be reckless in some ways."
