In the fifth round of the Cup, Derby County hosted Manchester United at Pride Park. A meeting that marked the reunion between Wayne Rooney and the Red Devils.
On this occasion, Ole Gunnar Solskjaer still had to compose without Marcus Rashford (back) and Paul Pogba (ankle).
Daniel James and Wan-Bissaka were also not on the trip. United found the opening just after half an hour of play.
After a cascade of strikes blocked in the area, Shaw attempted a volley which surprised Roos for the opening of the score (0-1, 34th).
Just before the break, Manchester made the break. Shaw found Ighalo in the area that was playing the defense before adjusting Roos (0-2, 41st).
In the last twenty minutes, the new Manchester United recruit had a double. On the right, Mata centered for the Nigerian striker who twice deceived Roos (0-3, 70th).
Thanks to this easy success, the Red Devils qualified for the quarter-finals of the Cup and will face Norwich.
