Lionel Messi's first goal against the Blues in the first-leg at Stamford Bridge canceled out Willian's stunning opener and handed the Blaugrana a slender advantage on the away goals rule going into tonight's fixture.
But Conte remains adamant that the Premier League giants can oust one of the tournament favourites if they are willing to rise up to the massive occasion.
"For the manager, for every coach, it is not simple to sleep a lot, especially before these types of games," said Conte. "I hope my players also have the same excitement [as me]".
Chelsea will hope to take inspiration from their 2-2 semi-final draw at the Nou Camp in 2012, which was the crucial result of their journey to their maiden Champions League title under interim-coach Roberto di Matteo.
However, the runaway LaLiga leaders will be able to recall two of the most influential attackers for the home fixture, as club-record goalscorer Lionel Messi and captain Andres Iniesta was included as part of the 25-man squad by manager Ernesto Valverde.
FC Barcelona: Ter Stegen; Roberto, Pique, Umtiti, Alba; Rakitic, Busquets, Iniesta; Messi, Suarez, Dembele.
Chelsea: Courtois; Azpilicueta, Christensen, Rudiger; Moses, Fabregas, Kante, Alonso; Willian, Giroud, Hazard.
