Valencia's David Albelda believes the current circumstances at Chelsea make it an ideal time to play Avram Grant's side.
The Blues are still wavering from the loss of Jose Mourinho and their current domestic form is well below their usual impeccable standards.
Just one victory in five Premier League games does not bode well for Grant's men, especially compared to Valencia's run in La Liga.
The Spanish side made it five league victories on the bounce on Sunday following their 1-0 win over Recreativo de Huelva.
Albelda is revelling in los Che's recent run of form and believes his side can claim all three points in the Group B UEFA Champions League clash on Wednesday.
"Now is a good time to play Chelsea. They have injuries and we are in a good run of form, especially in terms of results," he said.
Last season Chelsea knocked out Valencia in the quarter-finals of Europe's premier competition, but Albelda is confident that the midweek game at the Mestalla will have a different outcome.
"Last year we were very tired and not physically up for the challenge, but now things are very different," he added.
"Things are a lot easier now. In football you are judged by results and since we won in Germany things have changed and we have a lot more faith in ourselves.
"The problems at the start of the season have been eradicated. When results are bad this is what usually happens as it is much easier to blame the coach."
Meanwhile Valencia boss Quique Sanchez Flores has fitness concerns over goalkeeper Santiago Canizares and midfielder Manuel Fernandes.
Canizares is struggling with a leg injury and took only a minor part in Monday's training, while Fernandes had to sit out with an adductor muscle problem.
