LONDON -- There is something about Kai Havertz that makes it impossible to gauge the Chelsea forward's mood. Whether he is good, bad or indifferent, the 21-year-old carries the same unassuming expression like an impenetrable mask and it can hint at an air of indifference, which has not helped him at times during a difficult first season at Stamford Bridge.
To suggest he has struggled since his £62 million transfer from Bayer Leverkusen would be an understatement, but against Everton on Monday, the Germany international finally showed us why Chelsea were so determined to win the race to sign him.
