Jean Tigana has put yesterday's heavy defeat at Spurs down to tiredness and a lack of cutting edge in front of goal.
Reflecting on the 4-0 reversal at White Hart Lane, the Cottagers boss admitted his team had simply nothing left in the tank as they looked for their ninth unbeaten Premiership game.
"That is the first time we have lost by such a big margin," he said. "We had a bad day against an efficient side.
"It is the first time we have played three games in a week and the players were very tired today, they had no reaction and no legs left."
He added: "Our problem is that we need to score more goals and punish teams.
"Spurs had two chances in the first half and scored them both. We had two chances and missed them both. That is the difference at this level."
