Manchester United beat Liverpool 2-1 thanks to goals from Jadon Sancho and Marcus Rashford.
Man United passed the ball around the pitch in the first 20 minutes to set up Sancho's thunderous opener.
Erik ten Hag's club led 1-0 at halftime against an injured Liverpool team that has failed to win this season.
In the 51st minute, Martial assisted United's second goal. Mohamed Salah scored on a Fabio Carvalho shot, but it was too late.
The three of Sancho, Rashford, and Elanga/Martial did all the attacking damage to beat Liverpool.
Manchester United's defence featured Raphael Varane and Lisandro Martinez. They cleared 16 balls while attacking.
Martinez had a tough start, being substituted at halftime against Brentford, but he didn't need much time on the ball against Liverpool.
Liverpool had lost three straight games and was outworked at Old Trafford.
United opened the ten Hag era with a win in front of their home fans, who saw Casemiro's presentation and their first goal from open play.
