Inter Milan boss Gasperini pleased with victory over Celtic
"It was a shame we went down to 10 men before the break, especially as it changed the tone of the match," he said of Thiago Motta's double booking.
"We had everything we needed to put in a great 90-minute performance, but instead more than anything else it became a defensive approach in the second half. It was a good one, though, as we have solid foundations.
"Does Thiago Motta deserve a telling off? A little bit, yes. I know him well and am focusing on this player a great deal for this season."
