Show me some respect and remember what I taught you, Mourinho tells Villas-Boas
For Jose Mourinho the noise coming from north London on Friday morning was a question of respect. In Mourinho's estimation, Andre Villas-Boas has forgotten his manners.
Tottenham's manager has crossed an imaginary line, breaching Mourinho's trust by stealing his secrets and failing to show some appreciation along the way.
There was a sense at Chelsea's training ground that Villas-Boas should have left this playground squabble behind, or at least park it until Mike Dean has blown the final whistle at White Hart Lane.

But as a succession of coaches - from Sir Alex Ferguson to Pep Guardiola to Tito Vilanova and now Villas-Boas - have discovered, Mourinho always likes to have the final word.
'I'm not a kid - if I have something to discuss then we go upstairs, we have lunch and we speak about it,' Mourinho claimed.
'When people know me they can be very straight and very objective, but people shouldn't be wary of me because of my ugly face.
'It's a personal thing and I don't care about what he says. I'm not interested. I would say 90 per cent of the people who speak about me don't know me. The people who know me - their opinion is respectful. If they shoot for a positive or negative, they should make it public.

BUT WILL THEY SHAKE HANDS?
'The managers I don't know have no credibility. If there is a reason I don't like another manager I prefer not to say, but it's a question of personality.'
But Mourinho does want to know why the man whom he set up for a life in management at the very highest level after they worked together at Porto is taking cheap shots now that he is manager of Spurs.

He has every right to.
The Special One launched Villas-Boas's coaching career, taking him to Chelsea in 2004 where he was appointed opposition scout until they split at Inter Milan in 2009.
Chelsea's manager wants this done face to face, demanding an explanation mano a mano after he was accused of suppressing Villas-Boas's ambitions to become a coach.
There is a question of trust and loyalty, something Mourinho still values after working and learning from some of the best coaches in world football.

One of them was the legendary Dutch coach Louis van Gaal, who was outwitted by Mourinho in the Bernabeu when Inter Milan beat Bayern Munich in the 2010 Champions League final.
Mourinho added: 'I played in a Champions League final (against Bayern) where the manager was somebody very important in my career, somebody that gave me a chance to grow up and teach me things.
'When I played him in a Champions League final I did it in a professional way and he did it in a professional way. That's the way you have to do it.'
Mourinho served Van Gaal during his first spell at Barcelona between 1997 and 2000, soaking up the knowledge and the appreciation of the game from one of the undoubted masters.
The Portuguese coach gave Villas-Boas the same opportunities, holding his door open at Porto, where they won the European Cup in 2004, and Chelsea, where he became the opposition scout.
Villas-Boas followed him to the San Siro in 2008 and was wished well by Mourinho's coaching team when he left to become a manager in his own right at Academica the following October.
'Ask him, not me, whether I deserve credit,' added Mourinho. 'I have had so many assistants in my career and it's always an open book.
'I'm trying to do the same now with Chris Jones (fitness coach) and to Steve Holland (assistant first-team coach), people who are working with me for the first time. If they want to read the book or not, it's their problem, not mine.'
Despite their differences Mourinho is coming to terms with Tottenham's potential to play a significant role in the destination of this year's Barclays Premier League title.
Tottenham have made a solid start, level on points with Arsenal and boasting a 100 per cent home record at White Hart Lane.

Mourinho added: 'They are a big contender. This season they have the same manager for the second consecutive year and they were the champions of the transfer market. They bought a lot of players, and all of them are international players and players with quality.'
Villas-Boas knows that expectations are high and Saturday's clash with Chelsea is a test of their progress after a spectacular transfer window.
The Spurs coach added: 'The champions are struggling for points, but they have had a difficult fixture list.
'We are getting results and have not had a blip that would disturb our confidence. We have solutions that we probably never had before. With clean sheets there will be more motivation.'
If Villas-Boas needs even more, he can always glance across at Mourinho.
