Chelsea skipper John Terry is happy with his personal form this season.
Chelsea's meltdown under Villas-Boas corresponded with Terry facing trial for racism - a charge he denies - and an injury that looked set to rule the defender out until April.
Asked about the difficulties of remaining focused, he said: "I think I've shown that with my performances, despite what's happening off the field.
"If you had said 10 years ago that Robbie and I would be sitting here with such a big night coming up tomorrow, we'd have probably laughed at you.
"But that's the reality. You won't find two other people who care more about the football club going into this game tomorrow. We represent Chelsea.
"We give that fiery atmosphere in the dressing room and take it on to the pitch and hope everyone feeds off that.""I know what I have to do for Chelsea. As captain, I'm very fortunate and privileged.
