Chelsea’s midfield options are as strong as they come in the Premier League as it is, so Saul’s arrival would just be a big bonus.
Jorginho and N’Golo Kante have thrived under Tuchel and played a significant role in the club’s second Champions League win last season.
The German boss also has Mateo Kovacic and Ruben Loftus-Cheek to choose from in a highly competitive area of his squad.
Saul’s Atletico exit may not be entirely off the table yet, with Manchester United also linked with a late-window move for his signature.
But following the Red Devils’ capture of Cristiano Ronaldo, that possibility may now be void unless the club offloads players.
