Chelsea boss Andre Villas-Boas defended David Luiz after his error-ridden performance in defeat to Napoli.

Luiz's latest mistake was the most costly, gifting Napoli the third goal that made them firm favourites to win the tie.

"It's obvious that that player has become a target," said Villas-Boas.

"He's a fantastic young player with a big future ahead of him, and he has to work to try and be a bit better.

"We suffered three goals. If he's linked to one, he might not be linked to the other two."
