David Luiz is still talking to Chelsea about a new Stamford Bridge contract, says Maurizio Sarri.
Brazil defender Luiz's contract expires in the summer, with boss Sarri admitting the club have held discussions with the 32-year-old about an extension.
Chelsea snatched a 1-1 Europa League semi-final first leg draw at Eintracht Frankfurt, leaving coach Sarri admitting the Blues blew a big chance to take control of the tie. "I don't know on David Luiz, I know that he had a meeting four or five days ago, but then my mind was on this match," said Sarri. "I didn't ask him the result of it."
Luka Jovic headed Eintracht into an early lead, though Chelsea grew into proceedings with Pedro levelling on the stroke of half-time.
The Blues were left to rue a clutch of missed chances though, with Sarri insisting his side should have won. "I think we made a mistake in the first 20 minutes because my feeling was, from the bench, that we were playing only to manage the result for the 0-0," said Sarri.
"But we are not able to do that. Then we started to play after 25 minutes and played very well until the 85th minute and deserved to win for the number of opportunities.
"We were in control of the match for 70 minutes and should have won. But they are dangerous on the counter- attack if you give them spaces.
"We deserved to win, 1-1 is not so bad away. They are very dangerous at home, but are really very dangerous away.
"I've seen Eintracht's games in the Europa League and they are dangerous.
"We want to go to the final, but we know very well we'll have to play a very good match next week."
Eintracht boss Adi Hutter insisted his side can complete the job at Stamford Bridge in Thursday's second leg. "Everything is still possible," said Hutter.
"We have to score a goal, that's a fact, and Chelsea at Stamford Bridge will be the great favourites, for sure.
"But after the 0-0 draw here against Inter, no one thought we could go to Milan and win.
"That's how we have to act in London: be confident, brave and courageous."
Chelsea return to Premier League action tomorrow at home to Watford.
