Tottenham boss Ange Postecoglou admits he can't replace James Maddison.
The midfielder is facing a spell on the sidelines with injury.
"I dont think you can replace him but the system kind of adjusts to the individuals within it, we didn't create a system for Madders. We had a system and Madders fit into that he brought his own qualities to it," said Postecoglou.
"Whoever we bring in to replace him isn't going to be the same player, he'll bring different qualities to it, but it won't change our overall structure or intent in the way we want to play. It's just there's going to be some variances in there because of the nature of a different player being in there.
"I'm just disappointed for Madders. He's had an unbelievable start of the season, he's probably been one of the best players in the competition and he was looking forward to striving for more. I'm disappointed for him that that's been interrupted in the short-term."
