Jadon Sancho:
On the day when his World Cup hopes took a major blow, Sancho delivered the perfect response.
He is still to fully show his ability in a Manchester United shirt - but there have been flashes of his brilliance in the opening weeks of the season, as well as an increased potency under Ten Hag.
His goal showcased his impeccable close control and deadly finishing qualities.
Taking the ball on the edge of the area from Christian Eriksen, he quickly shifted it onto his left foot before picking his spot.
Manchester United need to see more of that - and so does Southgate if Sancho is to force his way back into the England manager's plans for Qatar.
These are early days under Ten Hag - and the winger still goes missing over periods - but it's now three goals for him this season and he is establishing himself as one of Manchester United's key forces.
Christian Eriksen:
The Dane just looks better and better with each passing game. He is the player Manchester United have been crying out for - probably ever since Paul Scholes retired.
Eriksen is the one who controls the tempo and is the most likely to cut open the opposition.
That's precisely what he did when suddenly speeding up the play and feeding Sancho in the build-up to the opener.
His dead ball delivery is also adding a new dimension to Manchester United's play.
Once he fully strikes up an understanding with Casemiro, it could completely transform the look of Ten Hag's midfield.
Cristiano Ronaldo:
He's had to wait for it - and when it came, it was from the penalty spot. But Ronaldo is finally off the mark for the season.
If he is unhappy with his lot after failing to secure a move in the summer, he is doing his best to get over the disappointment.
The effort is there and the smiles are back as well.
That's 699 club goals and counting. After opening his account, he will hope it's the turning point for his campaign.
