Real Madrid winger Vinicius Junior allegedly attracted interest from Chelsea earlier this season.
With a contract at the Bernabeu until 2025, club officials regard Vinicius as an important part of their long-term plans.
However, after making just 14 starts in La Liga and the Champions League this campaign, question marks remain over his future.
Despite their wide array of attacking talent, AS claims that Chelsea have recently enquired about the 20-year-old's availability.
Although that contact was made at the end of 2019, it remains unclear whether the Premier League outfit are prepared to up their interest in the coming weeks.
Kai Havertz is said to be on the brink of joining fellow attackers Hakim Ziyech and Timo Werner at Stamford Bridge.
