Andre Villas-Boas is unsure if he has the backing of Chelsea [ Images ] owner Roman Abramovich and wonders if he will be sacked in the same way as predecessor Carlo Ancelotti [ Images ] was last May, the Portuguese coach said on Monday.
"We are now in the exact same moment as last year," Villas-Boas told Portugal's TSF radio. "It is an exact copy.
"I think I have felt the confidence from Abramovich but ... the pattern of behaviour of the owner has led to a downfall (of coaches) in similar situations or even 'better' situations.
"What will be the reaction? It will be one of the two, a continuation of the project and full support or just the cultural pattern that has happened before. We don't know."
Villas-Boas has come under increasing scrutiny in recent weeks with Chelsea in the middle of a form slump and media reporting a rift with several players.
