Gullit reckons Roman Abramovich may need to replace the misfiring forward if the club are to challenge for honours this season.
The Dutchman, 50, said: “They wanted to give Torres a chance. Has he taken it? I don’t know.
“What he had done in the past at Liverpool and at Atletico was unbelievable. And he can’t do it for some reason. I don’t know why, I have no clue. It’s a mystery.
“But if he can’t do it then Chelsea need to do something else.”
