Double jeopardy rule explained: The reason David Luiz was sent off for Arsenal against Wolves

David Luiz's defensive frailties were exposed once again on Tuesday evening in the Premier League clash with Wolves.

With virtually the final kick of the first-half, the defender conceded a penalty for clipping Willian Jose in the area.

He was prevented from tucking the ball into the net by a foul from David Luiz, who was shown his marching orders.

The spot-kick was tucked home by Ruben Neves and Arsenal fans on social media were unimpressed - though many believed the officials had made a mistake.

Plenty suggested that the 'double jeopardy' rule should have been in effect, resulting in a penalty but not a red card for Arsenal's experienced defender.

However, that is not the case as it only applies to accidental challenges, which the rules state result in a yellow card, while it was obvious that Luiz knew exactly what he was doing.

The double jeopardy rule came into effect ahead of the 2016-17 season following an 18-month review by IFAB, football's lawmakers, led by former Premier League referee David Elleray.

It replaced the previous 'triple-punishment' rule, which saw players sent off, concede a penalty and handed a suspension for their dismissal.
