Manchester United clinched a 2-0 win over their Dutch opponents in Stockholm thanks to goals from Paul Pogba and Henrikh Mkhitaryan.
The victory came just 48 hours after the terror attacks in Manchester city centre.

And Herrera, who played a key role in the win, insists there are more important things than football.
