Havertz managed just one goal and two assists in the league since arriving from Leverkusen for a reported 71 million pounds , according to Premier League https://www.premierleague.com/players/20810/Kai-Havertz/stats?co=1&se=363 stats.
The 21-year-old was laid low by COVID-19 in November and was then used mostly as a substitute by manager Thomas Tuchel before picking up an injury last month. "It's been a tough season," Havertz said after Germany's 1-0 win over Romania in Sunday's 2022 World Cup qualifier."I know that things haven't been going smoothly."I think that things are going well right now so I don't want to overthink those negative impressions from the past. I am positive and hope that the next weeks will be every bit as good."
Chelsea are fourth in the league with 51 points and host West Bromwich Albion on Saturday after the international break.
