Inter Milan assistant manager Massimiliano Farris admits halftime changes made the difference for their 4-2 win against Roma.
Roma were leading 2-1 at the break before Inter stormed back with Marcus Thuram hugely influential.
Farris, who stepped in for suspended coach Simone Inzaghi, said: Roma had such a good start to the half and we conceded two avoidable goals in situations we had worked on in training.
However, the second half confirmed these lads are extraordinary. In the big games, they might get 20 minutes wrong, but they get it right back on track.
This should be a warning, though, because even a team like ours cannot believe this is enough, because the others are not letting go and anyone can cause us problems if we don't have the right attitude."
He continued: After the restart, we tried to use greater mobility to create that numerical superiority we needed to cause Roma problems.
The input we gave them was to find the positions of the midfielders and make the most of the wing-backs. This forced Roma to stretch out and they struggled on the wings. It was not easy.
We raised our level and these are extraordinary players who at the first sign of trouble were able to turn it around."
