PARIS, April 18 — Harry Maguire headed in the winner as Manchester United produced an astonishing extra-time comeback yesterday to beat Lyon and set up a Europa League semi-final against Athletic Bilbao, while Tottenham Hotspur are also through to the last four after beating Eintracht Frankfurt.

Maguire’s header in added time in extra time gave United a 5-4 win on the night at Old Trafford, and a 7-6 triumph on aggregate.

They appeared to be cruising towards the last four when, after a 2-2 first-leg draw last week in France, Manuel Ugarte turned in an Alejandro Garnacho cutback on 10 minutes and then Diogo Dalot fired home in first-half injury time.
