The much-awaited semi-final of this year's FA Cup lived up to expectations as Manchester United came down from a goal down to win the match and qualify for the FA Cup finals for a record-equalling 20th time.Dele Alli gave Spurs the lead after excellent work from Eriksen in the 11th minute. United refused to lie down and equalised through Alexis Sanchez after he was picked out perfectly by Paul Pogba with a beautiful cross.It was an extremely tight affair but United came out on top after Herrera gave them the lead with a brilliant shot in the 62nd minute after brilliant work from Sanchez and Lingard.It was an extremely crucial victory for Mourinho's men as they march into the finals.Here's how Twitter reacted.Goals first:Good tap in Goal by Dele Alli ⚽But the celebration really cracked me up😂😂😂 pic.twitter.com/TpSRD5D8MS— Regină ™ 🇶🇦 (@_RIZmadridista) April 21, 2018Brilliant performance by United Never mind the goals, the graft put in by both Sanchez and Herrera was exceptional 👏🏼#MUFC pic.twitter.com/KUuP6AOXwf— Laurie Hanna (@LaurieHanna) April 21, 2018Ander Herrera puts United ahead! #MUNTOT pic.twitter.com/ZZUiD4UY3O— Man Utd Goals 🎦 (@UtdGoals) April 21, 2018Laurels for United!FT! @ManUtd are through to the #FACup final after goals from @Alexis_Sanchez and @AnderHerrera help them beat @SpursOfficial @ManUtd 2-1 @SpursOfficial #MUNTOThttps://t.co/sD6FwzQYg6 pic.twitter.com/5WBKxFpSQT— FirstpostSports (@FirstpostSports) April 21, 2018There's not many who truly get what playing for Manchester United means, but Ander Herrera is most certainly one.
