The Catalan giants trail the Blues by one goal as they look to reach the final in Munich on May 19.
Xavi said the Barca are keen to avenge that defeat, as well as the one they suffered in the El Clasico.
"I wish we could play Chelsea on Monday," said Xavi. "We want to overturn the deficit against Chelsea and show we deserve to be in the final.
"I imagine Chelsea will be camped outside their own half so we will try to find spaces to 'open the can'."
