Former Israel coach Shlomo Scharf has taken another swipe at his nemesis, Avram Grant, after his appointment as Chelsea coach.

"He is a dangerous man, a manipulator, a coach who took the national team backwards in terms of football style and world ranking yet made the media think he did great," Scharf told the People.

"Now he has wormed his way in at Chelsea and the thought that Avram from (little Israeli club) Petach-Tikva is the next Jose Mourinho is unbelievable.

"He does not understand football and never will. He just has connections and his favoured journalists."
