Daniel Sturridge claims there is no division in the Chelsea camp, with the players as determined as ever to ensure the 2011/12 campaign is a success.

The Blues have come in for criticism of late, with disappointing showings in the Premier League and FA Cup offering little cause for optimism.

Andre Villas-Boas' side have slipped out of the top four in the league and were held to a 1-1 draw by Championship side Birmingham in the fifth round of the FA Cup on Saturday.

With each passing fixture now taking on added importance, a trip to Napoli in the Champions League on Tuesday night has become pivotal.

Sturridge refuses to buy into the belief that a midweek outing in Europe could make or break Chelsea's season, but he accepts that it is important for the squad to stick together and pull themselves through a tricky period.

"I don't think it is a defining week for the club but hopefully we don't get in the same situation as against Birmingham where we have to come from behind," he told the club's official website.

"We are all together as one and we are not a divided unit. We are a family and we've got a good unit going here and I think maybe we will see that in the next few games."

While Chelsea were toiling against Birmingham, Napoli were brushing aside Fiorentina with ease in Serie A.

Sturridge admits the Italian outfit, who have already beaten Manchester City this season, are a good side but he is adamant that the Blues having nothing to be afraid of heading into an eagerly-anticipated clash.

"They have some great individuals as well as a good team but we have the same and we are not going to worry about what they have got," added the England international.

"We have to go out there with the attitude that they have got to worry about what we have got. I am certainly not worried about that and we are going out there with the state of mind that we can win the game and play some good football, maybe get some more opportunities and put them away."
