Score: Burnley 0-1 Manchester UnitedGoalscorer: Anthony Martial with a sublime finish off Romelu Lukaku's superb assistManchester United went to Turf Moor and did to their denizens what they so often do to others, squeeze the life out of the game, win 1-0 with a solid, if unspectacular performance.Here, then, are the key talking points of the match:#5 Chris Smalling and Phil Jones out-Burnley BurnleyChris Smalling helped keep Burnley at bayThey are not the most lovable centre-back pairing, not even for the most hardcore United fan, but Smalling-Jones were able to do what so many have been unable to - dominate Burnley aerially.With their clearances agricultural at best, there was no question of United building play from the back, but what the two much-maligned (by myself included, I hasten to add) did today was keep the back-door shut, bully Ashley Barnes (not the easiest thing in the world) and ensure none of Burnley's runners ran onto any of the rare knockdowns the Burnley striker did win.Exactly the kind of players Jose Mourinho loves to have on his side.
