Chelsea fans were left disappointed with Kai Havertz's performance in their Premier League opener against Everton on Saturday. The Blues won 1-0, courtesy of a Jorginho penalty at Goodison Park.It was Thomas Tuchel's side's first win away against the Toffees since 2017. The Blues dominated the first half with 68% possession, attempting ten shots.However, it took a penalty to break Everton down. After Abdoulaye Doucoure fouled Ben Chilwell in the box, Jorginho converted from the spot to score what turned out to be the winner.The Toffees upped the ante in the second half, raising their possession to 42% and attempting five shots, with three being on target. However, they couldn't find an equalizer.While the Blues registered their first three points of the campaign, fans weren't happy with Havertz's performance. The German won just three of his nine attempted ground duels, committing three fouls and losing possession eight times. He was subsituted in the 75th minute for Armando Broja.Chelsea fans took to Twitter to express their disappointment at Havertz's performance:Matchday365@Matchday365Kai Havertz in the Premier League since August 2021 — excluding games vs. last season’s bottom three:• 21 games• 2 goals• 1 assist24492Kai Havertz in the Premier League since August 2021 — excluding games vs. last season’s bottom three:• 21 games• 2 goals• 1 assist https://t.co/WqAj66gnoNSam ⭐⭐@CFCSam47Havertz plays at half speed1Havertz plays at half speedJohnson@enyo_p_Havertz don tire me bro just can’t think fast enough2Havertz don tire me bro just can’t think fast enoughx@onextimeHavertz is a problem.

Or even what position he should play19727This will be Havertz third season and i’m still not sure what he’s good at. Or even what position he should playHavertz joined the west London side from Bayer Leverkusen in 2020 for €85 million but has had an underwhelming stint. He has scored 12 goals and provided six assists in 57 Premier League games.He did, however, score the only goal in their win over Manchester City in the 2020-21 UEFA Champions League final. With Romelu Lukaku re-joining Inter Milan on loan this summer, the onus will be on Havertz to be more clinical in front of goal.Premier League opening Gameweek so far as Chelsea beat EvertonThe 2022-23 Premier League season began with Arsenal winning 2-0 against Crystal Palace at Selhurst Park on Friday, August 5.Earlier today (August 6), title-contenders Liverpool were held to a surprising 2-2 draw against newly promoted Fulham at Craven Cottage.
