Andre Villas-Boas on Thursday night claimed that former mentor Jose Mourinho tried to block his progress as a coach and that they have not spoken in four years.
The Portuguese rivals meet in the Premier League for the first time on 
  Saturday lunchtime at White Hart Lane when Tottenham 
  take on Chelsea. 
And Villas-Boas has raised the temperature before the clash by revealing the 
  full extent of the bitter breakdown in their relationship, which the Spurs 
  manager says is beyond repair. 
“We had a great personal and professional relationship before that we don’t 
  have now,” Villas-Boas said at Tottenham’s training ground. “I don’t think 
  we need explanations on personal relationships and friendship. But our 
  relationship broke down. 
"I think we have mutual respect for one another and what we went through 
  cannot just disappear. But it’s not like it was before.”
Together with Steve Clarke and Brendan Rodgers, Villas-Boas is one of three 
  present Premier League managers who served their time as Mourinho 
  apprentices.
