Tottenham captain Heung-min Son says defeat at Fulham wasn't good enough.
Spurs were hammered 3-0 on the day.
Son said: "It is very disappointing and very frustrating. Everybody has to look in the mirror and say 'it is my fault'.
"It was not good enough. We didn't put in the effort we have put in this season. The performance, the attitude was not good enough.
"Everyone needs a big wake-up call.
"In the Premier League if you are not ready you get punished. Aston Villa are an amazing team, but so are Fulham. If you are not giving 100% you get punished. You don't get three points for free.
"This is two steps backwards. We now need to step forward.
"It is unacceptable, including me it was unacceptable. We are representing Premier League teams, we are representing Tottenham.
"This was not close to what we have been doing this season. It is very sad to watch this. The fans don't deserve this. They are coming here with positive energy and good vibes. Losing this was is very tough.
"The players are very down."
