Swansea City boss Garry Monk was left frustrated after defeat at home to Tottenham.
The Swans dominated for large spells after Wilfried Bony cancelled out Harry Kane's early opener, and Christian Eriksen's 89th-minute winner was harsh on the hosts who deserved at least a point from the encounter.
"We were on the front foot the whole of the second half and it's mesmerising at times how we didn't win that game, but it's a classic sucker-punch really for us," Monk said on Sky Sports 1.
"An individual mistake, giving the ball away when we should have cleared our lines, and obviously (we) get punished heavily for it.
"We didn't really deserve that but we come away with no points from a complete effort from us and (being) the only team that looked like they were going to win it."
