Despite polls indicating the UK would vote to remain in the EU, it was the leave camp that triumphed in a result that could have seismic ramifications.
The verdict has already had a damaging impact on financial markets, and Italy and Juventus defender Chiellini - who has a degree in economics - was asked about the vote ahead of the Euro 2016 last-16 clash with Spain.
“It’s a story which shocked everyone this morning,” he said at a media conference.
“Yesterday we went to sleep thinking that Britain would remain in the EU. Unfortunately that didn’t happen, and I think the biggest concern is the domino effect that this choice could cause.
“I don’t think it’ll change the economy, the only concern is a referendum in other states. I’m sorry that, having worked hard to create Europe, this vote is a symbol of the discontent felt across Europe.
“We should come together, and look for a political solution for these problems.
“A referendum in Italy? I’m not convinced that Italy would support leaving Europe. When there’s discontent you vote for change, even without definitive plans and I think that’s what has happened in England.
“I’ve read so many things. It happened in such a short time and there’s sorrow for Britain’s exit from the European Union.
“Maybe it won’t change much, but it’s a bad signal from such an important nation.”
