Tottenham boss Andre Villas-Boas has insisted he has no regrets over ending his "outstanding" working relationship with Jose Mourinho.Villas-Boas conceded in the summer of 2012 that he had not spoken to Mourinho for "quite some time". That impasse was broken two months ago at a League Managers' Association meeting which followed soon after Mourinho's return to Stamford Bridge. The two will not have a chance to help thaw their frosty relationship after Saturday's game with a glass of wine as Villas-Boas has to jet off to Porto as he is guest of honour at the club's 120-year anniversary dinner. Surprisingly, Mourinho, who guided Porto to Champions League glory in 2004, does not appear to be on the guest list. "I don't think Jose will be there," Villas-Boas said.
