Lucas Moura believes 'it's a time to be quiet' and simply work but also that Tottenham 'cannot be crazy' so early in the season.
After winning their first three Premier League matches, Tottenham have now lost their past three - all London derbies - and conceding three goals in each.
Sunday's 3-1 defeat at Arsenal brought an abysmal first 45 minutes and head coach Nuno Espirito Santo shouldered the blame afterwards and said he picked the wrong players for his gameplan.
Lucas admitted afterwards that the players just need to work hard and not speak.
"The feeling is very, very bad. We know what it means for the fans, for the club and of course we wanted to win, we wanted a different result," he said.
"It's not a time to speak. It's a time to be quiet and work hard. It was a very bad game, it didn't work at all. Like I said, it's time to work hard.
"I think they took advantage of our mistakes. We gave them too much space and we didn't play. We didn't try to play. We didn't try to have the ball. We have quality to have the ball, to build, to do more than what we did today. So many long balls. We were not aggressive enough and they punished us."
He added: "What I can say is we will work hard to improve, to do differently in the next game. We have the quality for this, to trust in our team, our squad, our manager. We will improve.
"We need to run more. We need to be more aggressive, we need to work more, work harder, but we cannot be crazy. It's only the beginning of the season. We have a lot of games to play so we need to improve as soon as possible."
When asked to pinpoint exactly what has gone wrong and in the Arsenal defeat in particular, he said: "We didn't have the ball. We didn't try to play.
"In my opinion, so many long balls and we weren't aggressive enough. So let's work for the next game, improve because we have more quality than this.
"It's the Premier League. Every game is hard, every game is a war. The first three games was good, especially against City.
"I don't know why we changed our mind against Palace, it didn't work. We didn't know how to react after but we need to react as soon as possible. We need to improve. Like I said, we have the quality to do better.
"We need to know how to pass this moment, how to face this moment. We're all good players who have quality to improve. To do better. That's the Premier League, that's football."
