Jose Mourinho's decision to part ways with David Luiz this summer was vindicated by pundits and fans during his dreadful performance against Barcelona in the Catalan's 3-1 victory over Paris Saint Germain in the Champions League quarter final first leg on Wednesday night (16 April).

The Brazilian international broke a transfer record this summer after becoming the world's most expensive defender when he left Stamford Bridge for the Ligue 1 side in a deal reportedly worth around £50m (€69.5m, $74.6m).

Having endured an uncertain spell at West London, being behind John Terry and Gary Cahill in Mourinho's pecking order, the deal looked then to be fantastic business for the Blues.

Luiz scored 12 goals in 142 appearances for Chelsea and had some excellent performances playing as a holder, but also cost points to the team with a number lapses in concentration and defensive errors when playing in the heart of the defence.

Some may argued about Mourinho's decision to sell him to PSG when he scored a memorable header against the Blues in the Champions League last 18 but his performance against Barcelona on Wednesday night vindicated the business again.

Pundits and fans on social networks mocked the Brazil international defender while pointing out that Luiz is an exceptional header but is far from worth £50m in defence, which is eventually the main task of a centre-back.

Luiz indeed had a nightmare against former Liverpool star Luis Suarez that would remind him of his horrible game against Germany during the summer World Cup, when he was at fault for three of the seven goals in the Brazilians 7-1 defeat.

The former Chelsea defender replaced Thiago Silva after 21 minutes and was nutmegged by Suarez twice to score Barcelona's second and third goal.

Former Liverpool defender Jamie Carragher reacted quickly on his twitter account.

Meanwhile, Manchester United legend Gary Neville speaking to Sky Sports said: "I think he'll be more than disappointed, Laurent Blanc, he really will. Luis Suarez, from an attacking point of view, was fantastic. But when you know you've got a player like him that will commit you, that will take you into the box if he can, you've just got to wait for help.

"You try and wait for your team-mates to get around, you delay, deny space and try and show him a certain way. He did everything he shouldn't do. He just carried on towards him and Suarez eight times out of 10 will stick it through your legs, or if not then around you the other side."

While fans on social networks mocked the Brazilian, Tottenham and England boss Glen Hoddle concluded: "He's a footballer who likes to play in the playground when there is no shape to the game. He is a talent but that's not what top football is about. For me he is a liability at the back, and he always has been. You have to find a place for him in midfield or even at right-back."
