Questions were asked about whether history would repeat itself when the champions slumped to a catastrophic home defeat to Burnley last weekend with just nine men.
But Courtois claims they have learned from Jose Mourinho’s disastrous 2014-15 campaign when it all went wrong for the reigning champs and the manager lost his job.
He said: “Obviously after last week, it shows it won’t be the same. We just started bad. Maybe we need as a group a little wake-up call and say: ‘Look, we need to give 150 per cent this year and not 100 per cent.’
“Obviously after last week, it shows it won’t be the same (as under Mourinho)”

“That’s what we did. I think we did very well. You see that in the end. We can win those difficult games.
“I remember two years ago we had to go to Manchester City and lost there, and it was a difficult start for us. Now, this victory is good.
“Next week we play at home against Everton, who are doing well. We don’t have the easiest start but this victory is good for the confidence, to continue the hard work we are doing in training.
“Can we defend our title? We will see. The Premier League is very long. Last year we didn’t start very well, we won the first games then we had a difficult September.
“Then a lot of people said we couldn’t win the league, and we did it. The Premier League is one long marathon, not a sprint of one month or two months.
“Let’s see, game by game, and then in May hopefully we are there to win the league. If not we will try to be as close as possible.”
Courtois also warned Chelsea’s title rivals that their best is yet to come when their squad is back up to full strength.
The Blues beat Spurs with two goals from unlikely hero Marcos Alonso in a belter of a game which ruined Tottenham’s start to life at Wembley.
And they did so without the injured Eden Hazard, the banned Cesc Fabregas and Gary Cahill, and with players like Tiemoue Bakayoko and Alvaro Morata not yet fully match fit.
Chelsea still hope to make up to four more signings this month, and Courtois said: “Well we play with some different players today than in May.
“Eden still has to come back, Bakayoko played his first game so physically he is not at this best but it was a very good game to start for him.
“We will try to work hard and maybe after the international break we know what is our full squad and we can build on that, play an amazing year and win trophies by the end of the season.”
Courtois claims Chelsea showed character and mental strength to bounce back in such style against a big rival, and that writing them off is a dangerous game.
He said: “Yes, I think so. I think we are doing very well, it was just a bit unfortunate that we had suspended and injured players, some players left, so it’s not easy for us.
“I think this victory for us is good to show as a team we are working very well and in the next weeks we can continue in this way.
“We are working very hard in training and that shows that the work pays off. For the group, this week we train very, very hard, that shows off today. That’s a pleasure for us and for the manager.
“Physically we dug very deep. Spurs, especially the last 15, 20 minutes of the first half, they had a lot of pressure on us. As well in the second half.
“Even if you see Marcos in the end, he was very tired, but still he made that run to score. You see that physically we are very good and for us that is important.”
