Chelsea's recent transfer record when it comes to strikers is a concern but they may have struck gold in Nkunku, who scored bags of goals for RB Leipzig and was the Bundesliga's Player of the Season in 2022. 9/10

Chelsea needed to overhaul their attack and Jackson is an exciting addition because while he doesn't have much senior experience he did boast the best goals per game rate in Europe's top five leagues for players 21 or younger last season. 7/10

Winger Gabriel is a highly-rated 18-year-old who became the youngest player in the history of the Brazilian top flight in October 2020 when, aged just 15 years and 308 days old, he made his debut against Fluminense in the Maracana Stadium. 6/10

Ugochukwu has made 47 Ligue 1 appearances for Rennes and has also featured in the Europa League but the 19-year-old is one for the future and Mauricio Pochettino has already said he could go out on loan this season. 5/10

France international Disasi will offer cover at centre-half and right-back for Chelsea and his versatility, coupled with his physicality and experience, may mean he gets plenty of action. 7/10

Sanchez will put pressure on Kepa at Chelsea after joining for £25m from Brighton, where he lost his place in the side last season after initially starting as first-choice. 5/10

Caicedo's huge move from Brighton could eventually be a British transfer record so expectations are sky-high that the Ecuador midfielder will become one of the best players in the world at Stamford Bridge. 9/10

Lavia was outstanding last season for Southampton as the 19-year-old looked composed and energetic for the Saints and he considerably adds to Chelsea's defensive midfield options this season. 8/10

Washington may have to wait for his chance at Chelsea but the young forward has a good pedigree having come through the ranks at Brazilian side Santos. 7/10

Chelsea don't seem totally convinced by Robert Sanchez and have signed Serbia international Petrovic to compete for the number one spot. Petrovic made a big impression in his one-year stay in the MLS, earning nominations for various awards, but faces a step up at Chelsea. 6/10

Palmer has excited in brief glimpses and caught the eye in the summer with goals for City in the Community Shield and European Super Cup. However, he remains a gamble for Chelsea having only started three top-flight games and is unlikely to play a big role for the Blues right away. 7/10
