Chelsea owner Abramovich agonising over Mourinho return: Can it work?
The Daily Express says Mourinho tops a shortlist of candidates to take over from Rafa Benitez at the end of this season.
A source close to Abramovich said: "Roman is not sure of Jose, because of the history between the two of them and what happened before.
"He is worried that the same things could happen again. He's still making up his mind."
