Inter Milan boss Jose Mourinho has warned Chelsea of his 'Stamford Bridge luck' when he faces his former club in the Champions League last 16 return leg next month. Mourinho helped Inter snap-up a slender lead over the Blues with a 2-1 victory at San Siro on Wednesday as he hopes to complete the job in London. "This time I will go back to a different dressing room, a different dugout, but I know normally Mourinho is lucky at Stamford Bridge," the Portuguese said. "We can go there with a legitimate ambition to go through," said the Inter boss. "The most important thing is the result and we are ahead. "It's not obviously the result which ends the tie, it's not 3-0 or 4-0, but no team is leading by two goals at this stage of the Champions League." Mourinho spent three successful seasons with Chelsea between 2004 and 2007, helping the London club to six different titles.
