The title looked certain to be Chelsea's until the events of last weekend, when Paul Scholes scored a last minute winner for Manchester United against their rivals City, and then the leaders were sunk at White Hart Lane.
Looking to bounce back: Frank Lampard battles with Tottenham's Luka Modric during their Premier League clash on Saturday
Lampard admitted: 'It's disappointing, especially with Manchester United's result.
'When they scored in the last minute it was hard. If they had drawn the game it would have left us in a very healthy position but now it's tighter.
'We were trying to get back into the game and with the last goal we had a bit of a lift but it's difficult with 10 men.
'But we have to get on with it now, understand it and not dwell on it because if we win our next three games we win the League.'
Chelsea goalkeeper Petr Cech doesn't believe much has changed after the events of Saturday however, saying: 'It is basically the same as before. If we had drawn we would be two points clear and we would still have to win every game. Now we have the first game at home to Stoke and we have to win.'
