Porto coach Andres Villas-Boas is under consideration at Chelsea.
AS says Chelsea owner Roman Abramovich is weighing up his options should he decided to replace Carlo Ancelotti in the summer.
Abramovich is seeking a young coach and Villas-Boas fits the profile.
Still only 33, he is currently the youngest football manager in the Portuguese league and would represent a risk for Abramovich.
The Russian also remains in touch with Real Madrid boss Jose Mourinho and would be open to bringing the Special One back to Stamford Bridge.
