“Borussia Dortmund changed their system to five at the back, which means they were afraid of us and wanted to play by changing their approach to mirror ours," Conte told Sky Sport Italia.
“We had prepared for a very different match, but did well to adjust. When Dortmund switched back to 4-2-3-1 after the break, we adjusted again and took control.
“We had prepared to press them in certain areas of the pitch and they changed their system, so that was no longer valid. The most important thing I told the lads was not to lose possession in central areas, as that is where they push forward on the counter.
