Petr Cech admits Chelsea have piled more pressure on themselves for Thursday's crunch clash against Tottenham by failing to beat Barclays Premier League strugglers Wigan.
Andre Villas-Boas' side had pulled themselves right back into the title race with three victories in a row, including over previously unbeaten Manchester City last Monday, prior to Saturday's disappointing draw at the DW Stadium.
Tottenham made the most of their rivals' slip with victory over Sunderland on Sunday, and Cech said: "It's not an ideal point because we wanted to have three, and we can consider it as two points lost, but we have another game at Spurs and we need to get those points ideally back."
He added: "Unfortunately when we are behind and chasing, any lost points puts you under more pressure to win every game.
"They have their game in hand, they are still in the top four and they are a direct opponent for the title and for the Champions League. This makes the game even more exciting."
Manchester City and Manchester United also pulled away from Chelsea this weekend, with Roberto Mancini's leaders now nine points clear of the Blues.
Cech knows the lost two points could prove crucial, but he said: "We will see at the end of the season.
"You can lose some points at the start and catch up, and sometimes you have a great start then you have a run with some games when you keep dropping points, so let's see. We were on a bad run, we turned it round, and we have to keep going."
