Chelsea striker Didier Drogba has fired a warning to all the candidates to lift this season's Champions League, saying they are going to have to produce something special to knock them out of the competition.
The Blues remain unbeaten this season both at home and in Europe after a 5-0 win over Schalke last night to ensure they top their group with a game to spare.
The striker told the London Evening Standard: "I don't know if other teams will want to play us. They will have to play well to beat us, just as we will have to, to continue this campaign.
"I think Chelsea have the chance to say they had great teams in terms of spirit, a machine in terms of hard work and efficiency (in the past).
"This one is efficient too, but with the attacking players, the passing rate and quality of passing is higher. We have more creative players, which makes it maybe better to look at.
"But the most important thing is to win titles, so this team will only be good if this team wins titles and big trophies. Then we will be able to compare it with previous ones."
Chelsea certainly have to be considered as the most likely of the sides from the Premier League who can become European Champions this season.
They have a manager with tremendous pedigree in the competition who has won the competition twice elsewhere, and has on three occasions led them to the semi-final stage - including last season during his first campaign back at the club.
After the money that was spent during the summer which has seen a complete overhaul of their forward options along with the notable addition of Cesc Fabregas in the midfield, it seems as those there is the required quality within the squad to get to the final in Berlin this season. The continued improvement from the likes of Willian, Oscar and Eden Hazard combined with the most solid back line in English football would mean that anyone will have their work cut out beating them.
Plus, there is the factor of Jose Mourinho. He has the tactical know-how to get the better of many of his opponents. When it comes to a managerial battle, there are very few that can outwit the Chelsea boss.
There is the formidable looking challenge from the likes of Bayern Munich and Real Madrid, but Chelsea will feel they are capable of beating them should they meet.
