Tottenham Hotspur head coach Mauricio Pochettino was bitterly disappointed after his side crashed out of the FA Cup.
Still fighting for the Premier League and still in the Europa League, Spurs were hoping to achieve a memorable treble but their hopes were shattered at White Hart Lane.
And the 43-year-old admits it is not easy to accept such an unexpected defeat at home.
"It was tough," Pochettino is quoted as saying by BBC Sport.
"It's like a Premier League game but you need to be clinical in front of goal. We managed the game, created chances but it was difficult to win.
"There was no tiredness. If we analysed the game we played better but you need to score. It's hard to explain.
"Mousa Dembele had a smaller groin problem. That's why we changed him at half-time.
"It's a tough period for us. We have a crazy schedule but now we need to look forward to be ready for next Thursday.
"It's impossible to know if losing here will help us in the long ruin.
"Now we feel disappointed because we're out."
