Chelsea manager Roberto Di Matteo has defended centre-back David Luiz after the club came in for criticism over apparent diving for a second successive week.
Luiz was booked for simulation in the second half of Chelsea's 2-1 win over Arsenal at Emirates Stadium on Saturday.
The incident followed a yellow card for Oscar in the Blues' 1-0 victory against Stoke in the previous week, while in the same game Branislav Ivanovic appeared to look for a spot-kick.
When asked about the Luiz's actions at the weekend, Di Matteo said: "David Luiz went down but he didn't appeal for anything. Sometimes they happen, sometimes they don't but he wasn't appealing for anything.
"I am against diving, absolutely. It's something we should eradicate from the game. It's probably not easy but if there's anything that can be done then we are for it. We've been trying to get goal-line video technology introduced and it has taken years."
On Monday, Manchester City's Sergio Aguero suggested referees make tougher calls on foreign players than their British counterparts in the Premier League.
