Goals from Argentine duo Diego Milito and Esteban Cambiasso either side of Salomon Kalou's equaliser ensured that the Serie A leaders take a slender lead to London for the return fixture on March 16.
And afterwards Mourinho claimed that Inter should now be able to hang on to their advantage courtesy of the Special One's superior home record during his tenure as Chelsea manager.
During his successful three-year stint at Stamford Bridge he never lost a home game in the Premier League, and was defeated on just one occasion in the Champions League - against Barcelona in February 2006.
"We know Chelsea well at Stamford Bridge... Mourinho doesn't lose at Stamford Bridge," he told Al Jazeera television.
However, in a a more pragmatic interview with Italian station Rai, he insisted that the tie is far from over
"The victory means a lot, and nothing at the same time. It is only the first half, and the second will be played in London." he said.
"On the pitch, there are things that we couldn't communicate to the players because the crowd was so loud.
"I will have to control my emotions for the return leg in London. We wanted to be aggressive and dominate the match, and our goals caused a reaction out of Chelsea."
