Ruben Amorim hailed Manchester United's 4-2 win against Brighton on Saturday as a "more complete" performance than their impressive victory Premier League champions Liverpool.
After going eight games in all competitions without a goal following his close-season move from Wolves, Brazilian forward Matheus Cunha netted in the first half at Old Trafford to start repaying his 62.5 million 83 million transfer fee.
Casemiro doubled United's lead before the interval and Bryan Mbeumo was on target in the second half.
Danny Welbeck's late goal against his former club and a stoppage-time effort from Charalampos Kostoulas came too late for Brighton to snatch a point.
Mbeumo struck again at the death to give revitalised United three consecutive Premier League wins for the first time since February 2024 under Amorim's predecessor Erik ten Hag.
