Holders Arsenal were surprisingly beaten by Watford at the Emirates Stadium on Sunday and Manchester United needed a late leveller to force a replay with West Ham.
Crystal Palace booked a Wembley date by beating Reading on Friday and Everton swept Chelsea away on Saturday with a brace from former Chelsea man Lukaku.
If West Ham beat Manchester United it will be the first time their have been three London clubs in the last four since 2002. Assuming Watford count as 'London'.
The replay at West Ham will become the last ever FA Cup ties at the Bolyne Ground with the Hammers moving to the Olympic Stadium next season.
The Semi-finals are at Wembley on Saturday 23rd and Sunday 24th April.
