Talking after the game, Son said [via The Daily Mail]: "Losing that game is unacceptable. We have got the lead five times in a row now. West Ham are always tough to play against but we were soft. In the Premier League, you don't know what will happen in the end. You have to kill a game. It's unacceptable. Players have to take responsibility – the fans don't deserve this.
"You have to play with more energy, especially at home. Whether we deserve it or not, we have to move on and bounce back. It's disappointing for the fans."
