Andre Villas-Boas insists Roman Abramovich is still happy with the job he is conducting at Stamford Bridge, despite Chelsea's recent slump.

The Blues have lost their last two games in the Barclays Premier League, with first Queens Park Rangers and, latterly, Arsenal getting the better of Villas-Boas' side.

The 34-year-old certainly realises a continued run of poor form could have serious repercussions, but he says the Chelsea owner is content for now.

"I've [been in contact] with the owner and people who surround him," said Villas-Boas. "At the moment he's happy."

Meanwhile, Villas-Boas has launched a staunch defence of his tactics amid criticism his attacking philosophy leaves Chelsea too exposed at the back.

This was clearly evident as the Blues were beaten 5-3 by Arsenal last Sunday, but Villas-Boas will 'fight to the death' to defend the ideals he believes in.

"We don't avoid our responsibilities for winning titles," added the Portuguese. "We think we can continue defending this philosophy and we'll defend it to the death.

"There is always room for [defensive] improvement but our most important task is to create more goal-scoring opportunities than the other team and put them in the back of the net.

"Our defence is solid, competent and we have complete confidence in it."
