Chelsea boss Jose Mourinho insists the current team can only be judged on trophies.
The Blues have enjoyed a blistering start to the new campaign - unbeaten in 12 Premier League matches, winning 10, while leading Champions League Group G.
"Only John Terry and Didier Drogba have won things with Chelsea, no one else in the team," he told reporters.
"These guys have to win if they want to be seen as a great team. They have to win. It is not just about playing beautiful football or being autumn champions."
Comparisons with Arsenal's Invincibles of 2003-2004 have been drawn, but Mourinho is remaining grounded.
He added: "When they win trophies we can compare them with other teams."
