Chelsea defender Gary Cahill insists that his side are full of confidence having returned to winning ways in the last week after a period of bad results.
Chelsea beat Fulham in the league last Saturday and overcame Swindon in the Capital One Cup on Tuesday having failed to win their previous four games.
With Jose Mourinho in the early stages of his second managerial stint at the club many were criticising the Blues especially after back-to-back losses to Everton and Basel.
But Cahill says that because of their recent wins the mood at Stamford Bridge is one of confidence ahead of this weekend's away match against Tottenham.
"It was a tough week, especially when we lost back to back," said the England.
"But we've responded really well. Two wins, two clean sheets. Happy days at the minute."
Cahill admitted that the squad have taken a while to adapt to the new style brought in by Mourinho which requires a defensive effort throughout the squad.
"He really expects you to defend and know where to be. Not just the back four, but everybody when we lose the ball," added the 27-year-old.
"I don't mind playing higher. It's difficult to play high against people with real, real pace. (But) I'm quite comfortable with playing high and I think the lads are."
In last year's White Hart Lane clash between Spurs and Chelsea it was the visitors who came away with a 4-2 win.
However Tottenham will be hoping for a different result this time round in order to preserve their excellent start to the season.
The north London side currently sit second in the table on goal difference to Arsenal, having won four of their first five games, with Chelsea sitting fifth on 10 points.
