Tottenham striker Harry Kane said: "It was amazing. It was a disappointing first half and we let them play. I went into the dressing room at half time and we knew it wasn't good enough. We said we had 45 minutes to give everything. When Lucas Moura scored the two you thought we would get another but then Jan Vertonghen hit the crossbar and we thought it might not be our day.
