Just three days after being appointed as coach, Davide Ballardini has steered his side to a huge upset as 10-man Cremonese eliminated Napoli from the Italian Cup.
Cremonese won a penalty shootout after playing most of extra time with 10 men after the match finished 2-2. They will face Roma in the next round.
Napoli midfielder Stanislav Lobotka was the only player to miss a penalty as he sent his spot kick wide in the pouring rain at the Stadio Diego Armando Maradona.
It was Ballardini's first match in charge of Cremonese after being hired on Sunday to replace Massimiliano Alvini, who was fired after 11 losses in 18 league matches.
Few gave Cremonese - bottom of Serie A - much chance against the runaway league leaders, who had thrashed mighty Juventus 5-1 on Friday.
But it was the visitors who took a surprise lead in the 18th minute when David Okereke raced down the left flank before cutting inside and rolling the ball across for Charles Pickel to slot home.
Napoli hit back with two goals in three minutes before halftime from Juan Jesus and Giovanni Simeone.
The home side looked set to ease to victory before a header from Felix Afena-Gyan with three minutes remaining saw Cremonese force extra time.
The visitors' chances of getting anything from the match appeared to diminish when defender Leonardo Sernicola was sent off 10 minutes into extra time following a second yellow card but they held on to emerge victorious from the shootout.
