The Europa League last-16 concluded on Thursday evening with contrasting results for the two remaining Premier League sides.
Arsenal crashed out as they were beaten on penalties by Sporting Lisbon following a tense 1-1 draw at the Emirates.
But there were no such worries for Manchester United, who cruised through to the Europa League quarter-finals after a 1-0 win away at Real Betis sealed a 5-1 victory on aggregate.
Former United manager Jose Mourinho is also still in the competition, with his Roma side overcoming Real Sociedad 2-0 over the two legs.
