Blagoja Milevski felt North Macedonia "won Italian style against the Italians" after his side sensationally ended the European champions' bid to qualify for the 2022 World Cup.
Aleksandar Trajkovski's long-range stoppage-time strike secured a stunning upset for the underdogs in a World Cup qualifying semi-final at Renzo Barbera on Thursday.
Italy dominated the game in Palermo, but failed to find the back of the net from 32 shots and were made to pay for their lack of a cutting edge.
Trajkovski's brilliant finish was North Macedonia's second shot on target as they set up a showdown with Portugal at Estadio do Dragao next Tuesday for a place in the finals in Qatar.
North Macedonia head coach Milevski felt his team played Italy at their own game.
"We won Italian style against the Italians, a goal from just two shots," he said.
"I'm very happy for this victory, I'm proud for these guys. All energy from tomorrow will be on Portugal.
"I am very happy for Trajkovski with his goal. The game was prepared in this way, we know that Italy are a great team with several champions but we played as we should.
"We know our strengths. Before the game I told the guys to have fun and they did just that."
North Macedonia have never played in a World Cup and will have to pull off another major surprise in Porto to beat a Portugal side that beat Turkey 3-1 on Thursday.
