A perfect hat-trick from Olivier Giroud helped Chelsea overcome Dynamo Kiev by easing into the Europa League quarter-finals with a 5-0 win to secure a resounding 8 -0 aggregate win and cruise into the Europa League quarter-finals on Thursday despite Maurizio Sarri's concerns about Dynamo Kiev's pitch. Chelsea had never lost a Europa League match by more than two goals and Dynamo manager Aleksandr Khatskevich admitted in the build-up that his side needed a miracle to overturn their deficit. Giroud took his tally to nine goals in as many appearances in the competition with his first treble in almost three years to become the tournament’s top scorer this season, the Blues got off to a flying start thanks to Giroud, as he scored twice in the first half, before Marcos Alonso made it three on the stroke of half time. The French striker made it 4-0 after 59 minutes when he headed home from a Willian free kick and Callum Hudson-Odoi added a fifth to cap an 8-0 aggregate victory for the Premier League side to put their name in the hat for Friday's last-eight draw. The perfect hat-trick – goals with his left foot, right foot and a header - was Giroud’s first for Chelsea and the win was the London club’s ninth in 10 Europa League games this season. The Blues will learn the fate of who they will play on Friday afternoon, with the draw taking place at 12pm. There will also be a semi-final draw, meaning they will know who they will face to get to the final should they get through the quarters.
