The 25-year-old believes that Roberto Di Matteo's side remain a strong team despite their 2-1 defeat to West Bromwich Albion in the Premier League on Saturday.
"From now on we think about Chelsea, as at this moment it is the most important test," he said. "We want to go through to the next phase of the Champions League.
"Chelsea lost to West Bromwich Albion on Saturday, but that doesn't change anything as far as we are concerned. On Tuesday we must step on to the pitch only to win."
Juventus are third in Group E, one point behind second-place Chelsea.
