Arsenal legend Emmanuel Petit has laid into David Luiz.

The centre-back signed a one year contract extension with the Gunners.

It is safe to say that Petit is not impressed, as he does not believe that Luiz has been a high level player for several years.

"David Luiz hasn't been a proper footballer for about three years," Petit wrote in a column for Paddy Power.

"But I'm not surprised that he has been given a new contract at Arsenal, because I've been very disappointed in relation to the club's activity in the transfer market.

"I've been particularly upset in relation to the defenders. We all know one of Arsenal's major weaknesses is their defence and nothing has changed. This makes me miss Arsene Wenger.

"If I was David Luiz, of course I would sign a new deal and I would also say a prayer of thanks to the Arsenal directors every time I wake up.

"Even when he last won the Premier League with Chelsea, he's not the same player any more. This guy has lost something.

"To be honest, it's a joke. Find some proper defenders. Are you telling me there are no young talented defenders on the market? I just don't get it."
