Chelsea are targeting free agents to succeed under pressure manager Antonio Conte.
Conte survived a crisis board meeting on Tuesday after their thrashing at Watford the previous night, but his job is still in doubt.
Le 10 Sport says Chelsea have Luis Enrique top of their shortlist while former Borussia Dortmund coach Thomas Tuchel is also under consideration. Both coaches are ready to take charge immediately.
Should results fail to improve, Conte will be sacked and the job offered to both men.
However, if the Italian lasts to the end of the season then other managers currently under contract will come into the equation.
