Chelsea captain John Terry believes that the team need to win silverware this season in order to prove that they're the best.
The Blues have impressed over the course of the campaign, with many tipping Jose Mourinho's side to clinch the Premier League title in May.
The team backed up that support by securing an emphatic 5-0 win over Swansea City on Saturday.
"Once again, we have top, top players, but until we go and win things, it's not there yet - that will be the test," the Daily Star quotes Terry as saying.
"At this stage, to be in all competitions is where you want to be. It's down to us big players to step up and let everyone else decide, that once we win stuff, we are a good side."
On Tuesday, the Blues will take on Liverpool in the first leg of the Capital One Cup semi-final at Anfield.
