#3 The young contingent keeps on improving
Under Frank Lampard's guidance, Chelsea finished in the top four in the Premier League in 2019-20. The former manager's biggest success from his time at the helm was the integration of youth into the first team. Mason Mount and Reece James, who were handed first-team debuts by Lampard, are now mainstays in the Chelsea side.
Thomas Tuchel has publicly stated how impressed he is by Mount. The 22-year-old midfielder is the first name on the teamsheet. He also won the Fan's Player of the Year award in 2020-21. Reece James has also continued to impress on the right hand side.
Mount and James went from strength to strength as last season progressed. While Mount provided Havertz with an assist in the Champions League final, James did a brilliant job of handling Sterling defensively on the night.
They are a long way from reaching their peak, and will definitely continue to improve in the 2021-22 season too. Additionally, other academy stars Callum Hudson-Odoi and Andreas Christensen could also play prominent roles for Chelsea in the upcoming season.
Undoubtedly, there is plenty of potential waiting to be tapped into at Stamford Bridge. If Tuchel can find the right recipe, Chelsea could become serious contenders for the Premier League.
#2 Imminent arrival of Lukaku adds new dimension in attack
Romelu Lukaku is reportedly very close to signing for Chelsea from Inter Milan. The 28-year-old striker is set to become the most expensive player for the club he left permanently in 2014. Interestingly, Lukaku ranks 20th in the all-time Premier League goalscorer list from his time at Everton and Manchester United.
Lukaku is a strong and lethal striker, which Chelsea have been lacking since the departure of Diego Costa in 2017. He is also Premier League proven, and at the peak of his career.
The Belgian will look to be on the end of the incredible amount of chances Chelsea create. He will also have a positive impact on other players such as Werner, Havertz and Ziyech. Lukaku led Inter to the Serie A title in 2020-21, and will be looking to replicate that with Chelsea in the 2021-22 Premier League.
#1 Tuchel has revived hunger for success at Chelsea
Thomas Tuchel, from his very first interview as Chelsea manager, has insisted that the squad is ready to compete for titles. This is a massive change in mentality, as his predecessor Frank Lampard often downplayed the team's capability to compete for trophies.
Tuchel delivered on his promise by winning the Champions League. The squad seem to be buying into the German's mentality too. The players no longer consider themselves underdogs and head into every game wanting the three points.
The tactician has successfully taken the side's ambitions to a new level. The Champions League triumph has further fueled the players' belief in terms of winning the Premier League title.
Since Tuchel's arrival, Chelsea have been one of the best sides in the league. His record against other top teams is impressive, having got the better of Pep Guardiola three times in the space of two months.
With a full pre-season of coaching for the players, Tuchel will expect performances of an even higher level from his side.
Based on the evidence of his first few months at Chelsea, it is safe to say Tuchel has revived the hunger for success at Stamford Bridge. That could make a massive difference in their pursuit of the Premier League title next season.
