David Luiz has refused to engage in a war of words with Unai Emery after the Spaniard questioned the attitude of some of the Arsenal players during his time in charge at Emirates Stadium.
Emery was sacked in December after guiding Arsenal to their worst run of results since 1992 and has since been replaced by Mikel Arteta, who picked up his second league win on Sunday when Newcastle were seen off 4-0 in north London.
Emery has given several interviews since leaving the Gunners and in one of them, while speaking to France Football, he suggested that certain unnamed players were largely to blame for what went wrong.
