Jose Mourinho and Pep Guardiola must pit their wits against each other once again after Manchester United were drawn at home to Manchester City in the fourth round of the EFL Cup.
Having resumed a rivalry that turned extremely sour in Spain when they were in charge of Real Madrid and Barcelona, Guardiola claimed the early bragging rights with a derby victory in the Premier League earlier this month.
And now the pair will clash again when holders City visit Old Trafford in the week of October 24.
The Manchester derby was not the only heavyweight tie, with Liverpool and Tottenham also set to do battle for a place in the quarter-finals.
Meanwhile, there will be a London derby between West Ham and Chelsea, who won a dramatic third-round tie against Leicester in extra-time on Tuesday.
Norwich’s reward for beating Everton at Goodison Park is a trip to Elland Road to face Leeds while Preston, who took the Premier League scalp of Bournemouth, will travel to Newcastle.
Arsenal host Reading while Hull travel to the south west to face Bristol City and there is an all-Premier League clash between Southampton and Sunderland.
