Full-time: Manchester United 3-1 Liverpool
- Anthony Martial scores on his first appearance since a £36m move from Monaco
- Daley Blind had given the hosts a 49th-minute lead before Ander Herrera notched from the penalty spot following a poor challenge from Joe Gomez
- Christian Benteke produces a stunning acrobatic finish but his late effort proves in vain
- David de Gea returns for his first Manchester United start of the season after signing a new four-year contract
- Wayne Rooney misses out with a hamstring injury and is replaced by Marouane Fellaini
So after a truly tedious first half, these two teams serve up a delightful second 45 featuring three superb goals from Blind, Benteke and Martial. The Belgian's in particular was an absolute delight, but most of the headlines will no doubt focus on United's new number nine.
Van Gaal's side up to second behind rivals City now and ahead of Arsenal on goal difference, with a trip to Southampton to come on 20 September after Memphis' Champions League reunion with former club PSV Eindhoven in midweek.
As for Liverpool, Rodgers' tactics and certain formation/personnel decisions continue to perplex. They are down to ninth and travel to Bordeaux in the Europa League next before hosting newly-promoted Norwich.
That is all we have time for tonight, but join us tomorrow as we provide live coverage of Sunderland v Tottenham from the Stadium of Light. Until then, goodnight.
Manchester United 3-1 Liverpool
Four minutes of additional time signalled, but you have to imagine that Martial goal has done enough to secure victory for United.
Well, well, well. Many eyebrows were raised when United swooped late in the window and committed a huge sum to sign Martial, but he has just provided a real glimpse of his obvious potential.
After receiving possession from Young, the pacy 19-year-old drifts inside and slides effortlessly past the likes of Skrtel and Clyne before finishing coolly past Mignolet into the far corner. What a way to introduce yourself.
Goal: Manchester United 3-1 Liverpool (Anthony Martial)
United were looking relatively comfortable with that two-goal cushion but suddenly they are under a bit of pressure following a truly wonderful strike.
After Ibe looks to take on Young, he stands up a cross that is headed high into the air by Blind. Benteke watches it every step of the way and, despite pressure from Herrera, produces a tremendous acrobatic finish reminiscent of Rooney's overhead kick against Manchester City back in 2011.
Goal: Manchester United 2-1 Liverpool (Christian Benteke)
Not content with simply blending in following his big-money move, Martial has chosen to sport a pair of extremely garish pink boots this evening.
De Gea is forced into a strong one-handed save as substitute Ibe tries his luck with a stinging shot.
The ball breaks for Milner down the right-hand channel. He sends in a cross towards Benteke, who rises above Smalling and Blind but powers a header over the top.
Divock Origi is sent on by Rodgers, with Ings eventually going off after some confusion surrounding the fourth official. Milner booked for a wild tackle on Young.
A third and final change from Van Gaal as Carrick is replaced by Schneiderlin. Darmian is then cautioned for a cynical foul on Ings, but Milner sends the free-kick wide.
With regular penalty taker Rooney not involved this evening, Herrera dusts himself down and blasts the spotkick into the roof of the net. Mignolet simply had no chance to save an effort struck with that sort of power, despite diving the right way.
Goal: Manchester United 2-0 Liverpool (Ander Herrera)
The hosts have a penalty as Gomez recklessly slides in on Herrera, despite the Spaniard not posing too much of a threat.
An air of expectancy around Old Trafford as Martial comes on for his United debut. Mata jogs off.
Rodgers also makes a change, with Jordon Ibe replacing Firmino.
Quick defending from Darmian to deny Benteke a clear run at De Gea. From the resulting corner, Skrtel's header deflects off Ings and produces a brilliant goaline block from Blind. The Dutch international then comes away from the post to ensure Firmino cannot provide a simple finish as the ball comes back across the six-yard box.
Lovren concedes a free-kick in a central area and protests furiously against the decision. This time it is Mata who provides the dummy, but Young can only bend the ball over the bar with his right foot.
Liverpool are throwing a bit of a caution to the wind now as Ings, who has spent much of this game in an unfamiliar withdrawn role on the left, breaks into the box and sees his effort tipped wide by a sprawling De Gea.
A cleaner contact on that shot and the visitors would surely be celebrating an equaliser.
De Gea has been completely untested on his return to the starting XI and his rustiness shows as he miscues a clearance straight to Can. Clyne then feeds Firmino, but Smalling makes a vital interception before Benteke can provide the tap-in.
Not a bad impact from Young. Replays of the goal show that Schweinsteiger helped immensely by occupying/smothering Clyne and clearing space for Mata's pass to reach Blind.
A sliding Milner tried in vain to block the shot, but he arrived too late.
It's extremely puzzling as to how Liverpool allowed Blind to reside in that much space. Perhaps they did not consider him much of a threat. Regardless, they have been undone by a textbook training ground routine and will have to show far more courage if they are to get back on level terms.
The resulting free-kick leads to the first real chance and the opening goal of the game. Young runs over the dead ball before Mata squares it to the waiting Blind, who thumps an excellent strike beyond Mignolet and into the top corner.
