Chelsea boss Frank Lampard admits their rivalry with Leeds United may be lost on his new players.
Lampard also questions whether Leeds will be using the game's history as a motivation.
"I'm aware of the rivalry myself from being a Chelsea player for so long and I know how the fans feel about it," Lampard said in the build-up to the game. "That's football rivalry in the Premier League between two huge clubs with a history.
"It's hard for me to equate that history when I talk to certain players like Timo Werner or Kai Havertz. They don't know the history so they can only look at Leeds at face value and see a very well-managed team that play with incredible energy and speed in their game.
"I don't know if rivalry will come into it or not but it will be a competitive match because that's how Leeds approach games these days."
