#3 Fred
You could mark Fred down for his red card in stoppage time but he was otherwise a beast in the midfield in this match.
The Brazilian stopped Atletico in their tracks several times with timely interceptions, and he sure has a knack for solid tackles.
Fred dealt well with Joaquin Correa and Alvaro Morata, although the latter got the better of him late on by squeezing the ball past him to set up Felix for the winner.
Tempers flared between the players in the dying moments when the 29-year-old tipped the Spaniard from behind, earning himself a second yellow and a sending off. Otherwise, a fine display.
#2 Anthony Martial
Anthony Martial led superbly from the front, always biting at the heels of Atletico's defenders and making electric runs on the break.
He missed a great chance to put Manchester United in front early on but it didn't unnerve the Frenchman, who continued to press forward.
With a little more cutting edge, he can truly unlock his potential as Martial looks set for a season of resurgence at Old Trafford.
#1 Tyrell Malacia
Undoubtedly the star of the show today, Tyrell Malacia was on fire. The 22-year-old was a thorn in Atletico's face with high press and brilliant link-up play, while also coming up trumps defensively.
His overlapping runs down the left were a cause of concern for the Rojiblancos as Malacia linked with Marcus Rashford to devastating effect and created some wonderful openings.
The most impressive aspect of his game was his passing range and he sure can keep his cool under pressure. The youngster maneuvered his way out of trouble early on with some neat footwork before sending a superb ball forward for Bruno Fernandes.
Signed from the Dutch side Feyenoord, Malacia has made a good impression during the pre-season. Manchester United fans can only hope that he's able to translate this form into the actual season too.
