Are you for real? Riley, Varela and Andreas had barely featured for us. Depay was still 21 and Lingard had played 10-15 times until then. But, yeah, lets ignore facts and go on about how "it happened under Fergie, too".
Depay was 22 and had played 150 matches for PSV
Lingard was 23 and had made a breakthrough at United - after playing more than 50 matches in the Championship
Varela was inexperienced yes - but he was 23 years old
They played together with Blind, Mata, Schneiderlin, Herrera who were all regulars
Today we had Tuazebe 21, Gomes 19, Rashford 21, Greenwood 17, Dalot 20 and Chong 19 - accompanied by 4 players the majority of United-fans accept arent good enough (Rojo, Matic, Jones, Fred). We started today with 6 players under 22. Against MidtJylland we had 2.
As for Andreas - he came on with 4 minutes left to play in Denmark
