For the third league game in a row, United's vaunted attacking trio failed to create more than one or two half-chances over the course of the 90 minutes, a woeful return for such a collection of talents.
Robin van Persie missed the opening loss to Swansea but since then he, Wayne Rooney and Juan Mata have consistently failed to combine and dovetail in any meaningful way over the last two games. The growing pains of the three-man defence have received all the attention but arguably it is the dysfunction in attack that should be Louis van Gaal's greater long-term worry.
Against Burnley it took 75 minutes for captain Rooney to muster a shot at goal (an off-balance header that was always going wide), while their most dangerous outlet generally seemed to be right wing-back Antonio Valencia.
Late on, when Valencia started getting in dangerous positions down the right, no-one was on hand to get on the end of one of his crosses.
Van Gaal told BT Sport after the game (per The Independent):
We are not giving (away) a lot of chances, today in the first half maybe two and in the second half maybe two.
In the games we played earlier, we didn't give a lot of chances away, but we have to create more chances and today we have created chances to score and that is where we have failed.
Rooney, Van Persie and Mata never managed to string an attacking move together (admittedly, a couple fell apart at the final pass) and that will be of deep concern to Van Gaal. Mata in particular might need to produce something tangible in the next few games if he wants to retain his place in this starting XI.
