John Terry has rubbished talk Chelsea are a club in crisis but has admitted things are bad at Stamford Bridge at the moment.
The Blues have gone from being runaway title favourites to fighting for a place in the top three in recent weeks after just one win in their last six Premier League encounters.
Manager Carlo Ancelotti has come under pressure for the Blues' recent run of poor form, with rumours circulating he could soon get the chop after Wednesday's 1-0 defeat to Marseille.
With games against Tottenham, Manchester United and Arsenal to come December is shaping up to be a tough month for Chelsea.
However, Terry believes the Blues will prevail in the face of adversity and is relishing the trip to White Hart Lane on Sunday.
The defender said:"We won't fold. No chance.
"I certainly won't, the manager won't and we have big characters like Didier Drogba and Florent Malouda, who have been at the very top for the right reasons.
"They are world-class players and big characters. It is time for us all to stand up.
"These are tough games coming up but we have big players here. Hopefully they are prepared to rise to the challenge and put their necks on the line."
