The Serie A champions face Celtic at Parkhead on Tuesday in the last 16 of the Champions League, and many of the Bhoys' fans had hit out at the Italians for using their Glasgow rivals' Murray Park ahead of the match.
However, Conte insists that he cannot understand what all the fuss is about.
"It was only really through the Italian press that I learned that there was such surprise and astonishment here in Scotland that we had used Rangers training pitch," he said.
"I have to say I found some of the criticisms rather strange. The choice was a purely technical one.
"The clubs were able to reach this agreement. We needed a training pitch with two goalposts and as far as I'm concerned that's it."
