Chelsea boss Andre Villas-Boas denies his team has a discipline problem.

Despite his side racking up a further six yellow cards in defeat at QPR, as well as their fourth red of the campaign, Villas-Boas denied Chelsea had a discipline problem.

"It's not indiscipline, it's not aggressiveness," he said.

"There might be tactical fouls, that you have to allow. You have to respect.

"We didn't ever lose our discipline. We committed fouls because we were exposed, but that's not indiscipline."
