I did it in about 1 hours 15 mins last week.About 2 hours, train to Victoria, tube Green Park (Victoria line) change tube to Wembley Park (Jubilee Line)
Just check for maintenance on tube lines
And hope it doesn't go to extra time or pens 😯🙊Its getting away from the Stadium that will be the problem, allow yourself time to queue for at least 30 mins getting into the station.
