Debutant Alexis Sanchez helped steer Manchester United into the FA Cup fifth round with two assists as Jose Mourinho's men eased past Yeovil 4-0.
The Chile forward laid on goals for Marcus Rashford and Ander Herrera, with Jesse Lingard and Romelu Lukaku glossing the score late on at Huish Park.
Sanchez's former club Arsenal spent the day assuming responsibility for the 29-year-old inadvertently missing a drugs test on Monday, as he dealt with the logistics of his United transfer.
The striker himself ended the night by ensuring manager Jose Mourinho tasted victory on his 55th birthday and the occasion of his 100th match at the United helm.
