The 21-year-old helped justify his massive transfer fee by scoring the biggest goal of his club career in Porto
Chelsea goalscorer Kai Havertz said he didn't "give a f*ck" about his price tag after scoring a Champions League-winning goal against Manchester City on Saturday.
The Germany international got on the end of a long Mason Mount pass near the end of the first half and rounded Ederson before slotting into an empty net.
The goal would hold up in a 1-0 win, helping to justify the £70 million ($95m) transfer fee Chelsea paid Bayer Leverkusen for Havertz last summer.
