West Ham United's reward for Monday's 2-0 Emirates FA Cup victory over Derby County is a trip to Manchester United in the competition's fifth round.
Monday night's draw pitted the Hammers against the Red Devils, who booked their place in the last 16 with a 3-1 win over Reading on Saturday evening.
The fifth round tie will be played in the midweek commencing Monday 27 February.
West Ham have been drawn with Manchester United on ten previous occasions in the FA Cup, last winning in a fourth round tie in January 2001, when Paolo Di Canio famously scored the only goal of the game at Old Trafford.
