What was this year's best FA Cup quarter-final goal?
The 12 time winners will play Chelsea - who have won the cup five times since 2007 - after they beat Leicester City 1-0 in a quarter-final that saw the third and fourth-placed Premier League sides come up against each other, Ross Barkley's second-half strike ensuring the Foxes remain winless since the season's restart.
Whom will it end in premium tears for?
In-form Kevin De Bruyne calmly slotted home a 37th-minute penalty in what was scant reward for a dominant first-half showing.
For Arsenal, Mikel Arteta's men went into Sunday's game high on confidence following their ideal outing last time against Southampton in which they secured an away win and also kept a clean sheet.
Barkley, one of three Chelsea replacements during half-time at the King Power Stadium, turned home the victor at the near post in the 63rd minute following Willian's cross.
Striker Tammy Abraham had a goal ruled out for offside and then Barkley found space in the area to clip in Willian's measured cross past Kasper Schmeichel. City, meanwhile, have won it six times each.
Manchester United last played Chelsea at the semi-final stage in 1996 when Andy Cole and David Beckham scored the goals in a 2-1 victory, Ruud Gullit, shortly to succeed Glenn Hoddle as player-manager, scored for Chelsea against a side that went on to complete the Double by beating Liverpool in the final by virtue of Eric Cantona's victor.
The win extended United's unbeaten run in all competitions to 14 matches.
