Chelsea goalkeeper Petr Cech believes the club's "obsession" with winning the Champions League is a healthy one.
Chelsea owner Roman Abramovich has seen his club lift the Premier League title and FA Cup on three occasions apiece while the side have also claimed Carling Cup glory twice during his tenure - but Europe's top prize has so far been elusive.
The Blues were runners-up in the Champions League in 2008, when they lost to Manchester United on penalties, and the task falls on current boss Andre Villas-Boas, who took over in the summer, to try and match Abramovich's ambitions this season.
Ahead of Wednesday's meeting with Valencia, Cech said: "Show me a team of the stature of Chelsea, Man United, Real Madrid or Barcelona who is not obsessed with winning the Champions League. If they are not, I'd be surprised why they play in it.
"Even if you have won it before, you just want to keep winning the Champions League. Every season, the ambition is to win the competition. People always use the word 'obsession' in a negative way, which I'm amazed by.
"We are not obsessed in the way that, if we don't win it, we'll just go and shoot ourselves. That's not the case. We are obsessed with the Champions League because this is a great competition to win.
"In a positive way, we try to search for the victory. I think it's very good to have this 'obsession' because, if you're not hungry to win, you shouldn't play."
