Rome, March 16 : Napoli reached their first UEFA Champions League quarter-finals as they dominated Eintracht Frankfurt 3-0 in the last-16 second leg on Wednesday night, eliminating the German side 5-0 on aggregate. The Partenopei had one foot in the quarterfinals after winning the first leg in Germany thanks to strikes from Victor Osimhen and Giovanni Di Lorenzo, a Xinhua report said. The Azzurri showed no mercy at the Stadio Diego Armando Maradona, as they were firmly in charge and went ahead before the break when Matteo Politano floated a cross from the right and Osimhen jumped high to steer in a header. Osimhen doubled the lead minutes after the break, when Di Lorenzo rolled a cross for the Nigerian to slide home. The home side put the game to bed 10 minutes later when Piotr Zielinski was tripped down in the box for a penalty, which the Pole converted himself. Napoli joined Inter and AC Milan in the Champions League last eight, representing the first time since 2005-06 that three Serie A sides have reached the quarterfinals. /IANS
