Hudson-Odoi penned a new long-term deal with the Blues last September, but the Englishman has struggled to impress this season, scoring just once in 18 Premier League appearances.
Because of concerns about the development of Callum Hudson-Odoi at Stamford Bridge, the Blues are reportedly keen to sign the Bayer Leverkusen attacker Kai Havertz this summer.
According to outlet 90min, Chelsea has 'stepped up their pursuit' of Havertz as they are worried by their academy's product perceived lack of progress during the 2019-20 campaign.
Kai Havertz enjoyed an excellent 2019-20 campaign for his German club, scoring 17 times and providing nine assists in 43 appearances in all competitions.
The 21-year-old has less than two years left to run on his contract at BayArena, and it is thought that he will seek pastures new during this summer's transfer window.
Chelsea has already bought Hakim Ziyech and Timo Werner ahead of next season as Coach Lampard looks to build a team capable of challenging for the Premier League title.
