Former Chelsea boss Avram Grant has urged the club not to sack manager Andre Villas-Boas. The 34-year-old Portuguese, who was only appointed in June, has come under pressure after three defeats in five games left Chelsea fifth in the Premier League, 10 points off the top. But Grant told BBC Sport: "It's tough times there but they signed a coach that deserves support."The results are not so good but they need to give him time.They need to give him all the support that he needs. "It's one of the things you need to give a new manager, especially him because he's young. He's facing new situations."''
