Goals from Pedro, Willian and English youngster Callum Hudson-Odoi were enough for Chelsea to breeze past Dynamo Kyiv and take a firm hold of their Europa League tie.
Pedro's early opener gave the Blues confidence in what could have been a difficult and nervy game. Instead, Chelsea kept hold of the ball and launched attack after attack against the disorganised Dynamo defence.
Willian settled any nerves in the 65th minute with a wonderful strike and Hudson-Odoi finished the scoring with a late effort in the 90th minute.
Maurizio Sarri would have hoped his side could have taken more of their chances and buried the tie ahead of the return leg in Ukraine, but the lead is still one the Italian will be satisfied with.
