Swansea City boss Garry Monk was furious with his players after their 2-0 defeat at Leicester City.
Leonardo Ulloa opened the scoring at the King Power Stadium before Andy King made sure of the victory heading into added time.
Monk rapped: "That's when we lost the game - in the first 20 minutes we were outfought for the first and the second ball.
"I had explained all week to the players that the first 20 minutes were crucial when the crowd were on a high and their players motivated.
"We knew we had to do that but we concede a goal we are disappointed with after 15 minutes and credit to Leicester because they kept to their game plan which was simple but effective and they had the momentum."
