Tottenham boss Ange Postecoglou is looking at the collective as they prepare to take on Chelsea.
The North London club are top of the Premier League, but know they must improve even more to have any chance of staying there.
Postecoglou and Spurs will welcome Chelsea and former boss Mauricio Pochettino on Monday.
Previewing the match on Inside Spurs, Ange said: "It's a big game, a London derby and Chelsea, traditionally, especially in the last 10, 15 years, have been one of those sides who have been a benchmark for success.
"Anytime you play in these kind of games you look forward to them. The atmosphere will be great, we're at home, brilliant for us... all of our home games so far have been fairly exciting, real engagement from our supporters. I'm looking forward to it, it should be another big night for us.
"They are a good team with some outstanding individual players and we're going to have to be really strong from a collective point of view to overcome that.
"We don't want to turn it into an individual battle, because they have players who can really hurt you, quality all over the park, but, so far, we've been really good in home games, making it difficult for all opposition, limiting their ability to hurt us and also being threatening the other way."
