Kai Havertz

Havertz continued to impress during the following season, despite Leverkusen initially struggling in the league, and by the mid-way point of the campaign was the only player to have started every match for the club, scoring six goals along the way. On 26 January 2019, he became Leverkusen's youngest-ever penalty scorer when he scored from the spot in a 3–0 league win over Wolfsburg, aged 19 years, seven months and 16 days. The following month, he became the second youngest-ever player to achieve 75 Bundesliga appearances, behind Julian Draxler, when he started and scored in a 2–0 win over Fortuna Düsseldorf. On 13 April, he scored on his 100th appearance for Leverkusen to help the club to a 1–0 league win over Stuttgart. The goal, his 13th for the campaign, also saw him become the youngest player since Stuttgart's own Horst Köppel in 1967–68 to score 13 goals in a single league season. On 5 May, he scored his 15th goal of the campaign during a 6–1 win over Eintracht Frankfurt; a match which for the first time ever saw seven goals scored in the first half of a Bundesliga match. On the final day of the season, he became the highest scoring teenager in a single Bundesliga campaign when he scored his 17th goal during a 5–1 win over Hertha BSC. At the end of the season, he was named runner-up to Marco Reus for the German Footballer of the Year award, losing out by just 37 votes.

On the opening day of the 2019–20 campaign, Havertz scored in Leverkusen's 3–2 win over Paderborn, becoming the second-youngest player of all time behind Köppel to score 25 Bundesliga goals. In December, at the age of 20 years, six months and four days, he broke another of Werner's records to become the youngest-ever player to reach 100 Bundesliga appearances when he started in his side's 2–0 defeat to Koln.

On 14 April 2018, Havertz became the youngest player in the history of the Bundesliga to reach 50 appearances at 18 years and 307 days old, breaking the record previously held by Timo Werner. He went on to end his second full campaign with the club with 30 league appearances and three goals to his name as Leverkusen ended the season in fifth place.

On 29 August 2018, Havertz was called up to Germany's senior team for the first time by head coach Joachim Löw. He was included in the squad for Germany's UEFA Nations League match against France and friendly against Peru. Havertz made his international debut on 9 September 2018, coming on as a substitute in the 88th minute for Timo Werner against Peru, with the match finishing as a 2–1 home win for Germany. Upon making his debut, he became the first player born in 1999 to represent the national team.

Following a 15-month absence from youth internationals, Havertz made his debut for Germany's under-19 team, debuting on 31 August 2017 in the 0–0 friendly draw against Switzerland, coming on in the 72nd minute for Palkó Dárdai. On 4 October 2017, in his third appearance for the under-19 team, Havertz scored four goals in a 5–1 win against Belarus in the first round of European Under-19 Championship qualifying. He was later named captain of the under-19 side.

Upon making his debut for Leverkusen in 2016, Havertz became the club's then-youngest ever debutant in the Bundesliga and he became their youngest ever goalscorer when he scored his first goal the following year. He is also the youngest player to reach the milestones of 50 and 100 league appearances in the German top-flight.

Havertz made his debut for Bayer Leverkusen on 15 October 2016, coming on as a second-half substitute for Charles Aránguiz in a 2–1 Bundesliga loss to Werder Bremen. Upon entering the field of play, he became the club's youngest ever Bundesliga debutant at the age of 17 years and 126 days, although his record was broken by 111 days by Florian Wirtz in 2020. On 17 February 2017, he assisted teammate Karim Bellarabi to score the 50 000th Bundesliga goal. Four days later, following the suspension of teammate Hakan Çalhanoğlu, he was handed his first Champions League start in the first leg of a round of 16 loss to Atlético Madrid. He was ruled out of the return leg of the fixture in March, however, as the match clashed with the examinations period at his school. He scored his first goal for the club on 2 April, netting a later equalizer in a 3–3 draw with VfL Wolfsburg. Upon doing so, Havertz broke another club record to become Leverkusen's youngest-ever goalscorer in the Bundesliga at the age of 17. He ultimately made 28 appearances across all competitions and scored four goals, including a brace against Hertha BSC on the final day of the season, as Leverkusen ended the campaign in 12th position.

Havertz was included in Germany's squad for the 2016 UEFA European Under-17 Championship in Azerbaijan. He appeared in all five of Germany's matches, scoring once before Germany were eliminated by Spain in the semi-finals.

Havertz made his debut for the Germany national under-16 team on 11 November 2014, starting in the friendly match against the Czech Republic before being substituted out in the 57th minute for Tom Baack. The match finished as a 3–1 win for Germany.

Havertz has been described as technically-gifted, two-footed midfielder who is comfortable with the ball on either foot and adept with his head. During his formative years, his style of play drew early comparisons to compatriot Mesut Özil, with Havertz himself admitting the Arsenal midfielder was a player he looked up to. By the age of 19, and following numerous impressive performances in the Bundesliga, further comparisons had been drawn between Havertz and former Leverkusen players such as Michael Ballack, Toni Kroos and Arturo Vidal, and German media began describing him as a combination of the lot and an Alleskönner – a player who can do everything.

Born in Aachen, Germany, Havertz received his first experience in football at the age of four when he joined amateur side Alemannia Mariadorf, where his grandfather, Richard, was chairman of the club. In 2009, he was signed by second division side Alemannia Aachen where he spent only a year in the club's academy before joining Bayer Leverkusen at the age of 11. In the years that followed, he had to overcome the challenges associated with growth spurts and in 2016, after scoring 18 goals for the club's U-17 side, he was awarded the silver U-17 Fritz Walter Medal before breaking into Leverkusen's senior side the following year.

Kai Havertz (born 11 June 1999) is a German professional footballer who plays as an attacking midfielder or right winger for Bayer Leverkusen and the German national team.
