Manchester United beat Ajax 2-0 in Stockholm courtesy of goals from Paul Pogba and Henrikh Mkhitaryan.

Dolberg drew a blank for the Dutch side but the 19-year-old has enjoyed a stellar season for the Amsterdam outfit.
He has netted 23 goals from 47 games and it seems his fine displays are now attracting the interest of Europe's elite.
