Chelsea manager Graham Potter needs to get the cogs whirring at Stamford Bridge, having lost the past three matches in all competitions, and will hope that the midseason break, making way for the World Cup in Qatar, will breathe fresh life into the side.

One of the most notable areas requiring improvement is the tip of the sword, the frontline, with the Blues’ 17 goals scored in the Premier League this season the lowest of any squad in the top-half. 

And while a centre-forward remains a position at the top of owner Todd Boehly’s shopping list, Kai Havertz is reminding the club that he possesses the spark that can alleviate the club’s current woes. 

Pierre-Emerick Aubameyang might have been the short-term answer to the club's centre-forward issues, signing from FC Barcelona this summer, but at 33 years old his presence at the front of the Chelsea ship will not last forever, and Havertz, ten years younger, possessing all the tools to flourish, if he can just unearth that vein of consistency.

Havertz, signed for £72m from German outfit Bayer Leverkusen, has only scored 27 goals and provided 14 assists in 112 appearances for Chelsea, failing to show quite the same goal-scoring prowess that saw him net 46 goals in just 150 outings in Germany. 

He did, however, score the winning goal as Chelsea defeated Manchester City 1-0 in the 20/21 Champions League final. 

And despite only scoring four goals in 20 appearances this season for the West London outfit, Havertz shone for Germany in Qatar despite a miserable group stage exit.

Boasting an impressive record of 12 goals in 33 outings for his country, the 23-year-old rebounded from a lacklustre display against Japan in the opener to star off the bench against Costa Rica.

Scoring twice in a 24-minute cameo, the £60m-rated phenom outperformed his expected goals metric of 1.36, as per Sofascore, hitting the target three times and missing the mark with a further two efforts.

Receiving a match rating of 8.9, and picking up a Man of the Match award, Havertz was a driving member behind the Germany comeback that oversaw a remarkable 4-2 victory, with his side 2-1 down when he entered the field of play. 

His tenacious, high-octane display does not always grace Stamford Bridge with its presence, but his integral role in forcing the Germany comeback was a reminder of why he attracted such a lucrative fee in 2020. 

Despite the intensity of the affair, Havertz only lost possession four times, accurately spraying passes and instigating forward transitions, reaching a teammate with 82% of his attempted passes.

He will need to emulate his form in Qatar when he returns to London, with Chelsea’s woes in dire need of remedy.

But his towering, explosive performance against Costa Rica reaffirmed to the world that he has a goal-laden spell lurking just around the corner, and should he carry that golden touch back toward Potter’s team, he could finally unleash the potential clearly bubbling just beneath the surface.
