Andre Villas-Boas admitted Chelsea paid for trying to hold onto to their slender lead after they conceded a late goal to draw 1-1 with Wigan at the DW Stadium on Saturday.
It was a doubly disappointing result for Chelsea after they had hauled themselves back into the Barclays Premier League title race with victory over leaders Manchester City on Monday.
Manager Villas-Boas said: "They were two completely different halves. The first 20 minutes of the second half we were good and it was a question of patience until we found the goal. We could maybe have tried to go for the second goal but we decided to try to hold onto the first and exploit the space in behind. But we conceded two minutes from the end."
