The German boss is looking to improve his squad ahead of next season, with the summer transfer window open set to open on June 9.
AS in Spain report that Niguez is a player that both Chelsea and Paris Saint-Germain have ‘in their sights’.
The 26-year-old made 33 appearences in La Liga in the 2020/21 campaign as Diego Simeone’s side lifted the league title.
The report claims that while in previous years, Atleti have been unwilling to let the midfielder go, that stance has softened due to the economic impact of the Covid-19 pandemic.
While no official approach from either club has been made as of yet, more clarity is said to be expected in the coming weeks.
Meanwhile, Bundesliga champions Bayern Munich and Manchester United have also been heavily linked with a move for Niguez.
Niguez was a notable omission from Spain’s 24-man squad for Euro 2020, with Luis Enrique opting for Marcos Llorente, Sergio Busquets, Rodri, Pedri, Thiago, Koke, Fabian, Dani Olmo and Pablo Sarabia as his midfield options.
