Tottenham boss Harry Redknapp admits the Champions League has thrown up a new challenge of his motivational powers.
Redknapp believes his current injury worries have not helped his side as they have struggled to balance their Champions League and Barclays Premier League commitments.
"The biggest problem you have is probably getting the players up for the Premier League games after the Champions League," said Redknapp, whose side have won just two of their six league matches this term.
"You have to juggle around your team, I've found and when you keep changing your team, it makes it difficult to get continuity.
"We've had to do that an awful lot - change the team - probably through injury more than anything, especially in the back."
Redknapp said: "Champions League is suddenly something fantastic, new, and then getting up again for the maybe more bread and butter games, they found difficult at Chelsea in the early days.
"But I think they've obviously come to terms with that now.
"So it's something we've got to make sure we do, get ourselves up for another tough game on Saturday."
