David Luiz
David Luiz is believed to be concerned over the Manchester United rumours.

David Luiz is reportedly concerned over his name being attached to a possible swap deal for Manchester United star Wayne Rooney, with the defender also being targeted by Paris Saint Germain.

Luiz struggled to find his feet for the Blues when he made the move to west London from Benfica in 2011 but last season as he became more disciplined and accustomed to English football the 26 year old helped create a much more consistent defensive structure in the squad.

But with Jose Mourinho coming into the fray rumours have suggested that the Brazil international is set for an exit, with his risky style of play coming up against Mourinho's style of management.

Manchester United were believed to have been offered the star in a player-plus-cash deal for Wayne Rooney but Chelsea have since venomously denied that such an agreement would take place.

And The Sun is reporting that Luiz is very concerned about the reports and doesn't fully believe Chlesea's public assurances that the player is not for sale.

Meanwhile, there are claims in France that the Brazilian is a target for PSG, with the club opening formal negotiations over Luiz and offering 40m for his signature.

Le10Sport say that Chelsea want €50m, €10m above PSG's own evaluation of €40m, but are willing to negotiate with the Ligue 1 outfit as Laurent Blanc looks to overhaul his defensive line-up.

Mourinho is keen to make his own mark on the Chelsea squad and has pinpointed Rooney as his number one target in the coming weeks. If the manager is willing to offload Luiz, it is possible he could have privately offered him to United, but David Moyes will no doubt demand a lot more than Luiz and £10m for a player who has been the heart and soul of United for the last nine years.

But should Luiz agree terms with PSG, he may no longer be a possibility to bargain with whether Chelsea have used him as a makeweight for Rooney or not.
