Jose Mourinho saluted his Manchester United players for hanging on to reach the Europa League final on a night of high anxiety at Old Trafford.
United went through 2-1 on aggregate but Celta Vigo equalised on the night in the 85th minute and would have gone through on away goals had John Guidetti converted a golden chance with the last kick of the game.
United defender Eric Bailly was sent off following a late melee – which also saw Celta's Facundo Roncaglia dismissed – and will miss the final against Ajax in Stockholm in two weeks' time.
