Former Chelsea captain Marcel Desailly says his old club needs to win the Champions League to take the next step.
Desailly has warned Chelsea they won't be as big as Manchester United or Liverpool until they win the Champions League.
He said: "Winning the Premier League and FA Cup in recent seasons has taken some of the pressure off the players.
"From the outside Roman Abramovich seems happy as long as the club is winning. But we all know how important the Champions League is. It's what Chelsea and the chairman want to get their hands on.
"It's what is missing. To have the stature of clubs like Manchester United, Liverpool, Real Madrid or AC Milan, you need to win the European Cup.
"That's what they've done and Chelsea haven't quite reached that level yet.
"Chelsea's exposure matches the others, but what's missing is a European trophy.
"You can't overestimate what it does for your profile around the world. I've been fortunate to win it twice and it has a massive impact."
