“I’ve experienced games without any fans allowed in when I was Italy coach and it’s a strange atmosphere which isn’t easy because it feels more like a training session,” Inter coach Antonio Conte said. “But the boys had the right approach and even after conceding we reacted immediately.”

The Ludogorets team had arrived at Milan’s Malpensa airport on Wednesday wearing protective face masks and gloves. Most wore the protective gear as they entered the stadium on Thursday as well.
