The Chelsea manager, Maurizio Sarri, wants to beat Pep Guardiola to the January signing of Jack Clarke from Leeds United, according to the Daily Mirror (December 6 liveblog, 07:03).
Guardiola, Sarri's Manchester City counterpart, is said to be a long-term admirer of the teenage Leeds winger.
And it is claimed that both clubs, Chelsea and Manchester City are ready to test the Whites' resolve with a firm bid for the player.
18-year-old Clarke made his debut for Leeds earlier this season, under a man Guardiola once claimed to be the world's best coach - Marcelo Bielsa.
And he provided his first assist in United colours on Saturday, enabling Pablo Hernandez to settle their Yorkshire derby at Sheffield United.
Leeds are, however, under little pressure to sell Clarke, whose existing deal runs until 2021.
And the Whites' promising league position - four points clear of third-place West Bromwich Albion in second - could convince the York-born talent to remain at Elland Road.
Both Chelsea (Jamal Blackman, Lewis Baker and Izzy Brown) and Manchester City (Jack Harrison) have loaned players to Leeds this season.
Could Chelsea or Manchester City prise Clarke away from Leeds?
