Chelsea boss Di Matteo explains mystery tactics for Juventus defeat
"I didn't want to give the centre-backs any point of reference," he said.
"I'd rather have Hazard, Oscar and Mata interchanging positions and trying to find the space.
"Hazard probably had the first good chance for us, Oscar the second and Mata also found himself in front of the keeper.
"In terms of that transition, we were very dangerous and created some good opportunities."
He added of fielding two right-backs: "I wanted to reinforce the midfield a bit, try to control the left side.
"The first goal was lucky for Juventus, a big deflection.
"The first goal is, a lot of times, decisive."
