Andre Villas Boas' future at Chelsea looks more uncertain than ever, with the club having confirmed that Roman Abramovich has had a meeting with the manager to discuss problems with the sides' performances.

The Blues fell to a 2-0 loss to Everton at the weekend, and as a result the club are now outside the top four, sitting just one point ahead of sixth-placed Newcastle.

And while Chelsea are still in contention for the Champions League trophy, sources at the club have told Sky Sports that Abramovich met with Villas-Boas on Sunday, as the club called off a scheduled break.

Abramovich is currently still attending court, but the Chelsea owner has reportedly made his feelings clear at Stamford Bridge that he expects more from the west London side, as they undergo rebuilding under Villas-Boas.

The news comes as former Chelsea striker Tony Cascarino claims that the manager will be worried about his future, particularly after such an underwhelming performance against Everton at the weekend.

"Villas-Boas is under pressure now," he told Talksport. "He's probably been given more time than most of the previous manager, others have gone for far less.

"The performance was awful, they were second best and outfought against Everton. You know what you're going to get at Goodison Park.

"I've watch Chelsea a lot and I'm scratching my head to work out who their best player is, everyone is underachieving at Chelsea, including the manager."

With FA Cup, Champions League and Premier League matches all coming up in the next two weeks for Chelsea, the team will be under maximum pressure to bring come close to a trophy under their new manager.

Villas-Boas himself admitted to Chelsea TV that the game at the weekend was not up to scratch, refusing to make excuses as Everton showed their dominance throughout the game.

"When you lose a game 2-0 and you are Chelsea Football Club playing for the Champions League and with big expectations, losing is not good enough and the performance was not good enough, that's why we lost," he said.

"We took so many passes side to side and we never really opened them up.

"In the second half, we tried to play more direct but they were fighting well and kept organised, and 1-0 up so early became so much more difficult to break."
