United showed an attacking fluidity that had been missing in recent games, with the scorers combining well with Adnan Januzaj and Angel di Maria.

The result is a miserable one for Leicester, as they remain bottom of the Premier League table.

United made a bright start to the match and looked to get the ball into the feet of either Van Persie or Falcao whenever possible.

Leicester, on the other hand, barely ventured into United's half. Leonardo Ulloa, playing as a lone frontman, looked increasingly isolated up top.

For all of United's possession, they found it difficult to create chances early on and Mark Schwarzer was rarely tested inside the opening 15 minutes of the match.

Van Persie found space inside the penalty area and played in Falcao rather than shooting himself, but the Colombian could not sort his feet out and Leicester cleared.

The first real chance of the game fell to Di Maria, who controlled the ball on his chest before volleying over the goal from 25 yards.

The opportunity sparked an end-to-end few minutes, with Jeffrey Schlupp spurning a good chance to put Leicester in front before Van Persie mishit a volley.

Van Persie didn't dwell on the missed chance, however, and fired home moments later to put United in front.

The goal gave United confidence and Falcao doubled United's advantage before Morgan's own goal made it three for the Red Devils just before the break.

Leicester might have lost confidence given the scoreline but they started brightly in the second half as Danny Drinkwater found himself inside the United area.

Ulloa was waiting for a tap-in, but the midfielder badly overhit his cross and the danger was cleared.

The same player was then presented with an opening following a clearance, but Marcos Rojo did well to neutralise the danger and clear.

Marcin Wasilewski grabbed a late consolation for the Foxes, but it was too little too late as United closed out the win.
