Nicolas Anelka has hit out at former Chelsea manager Avram Grant, saying: "He used to look down on me."
The 31-year-old will come up against his old boss, who managed him for six months back in 2008, when the Blues face Portsmouth in the FA Cup final later today.
The Sun reports in his new book, Anelka, published on Sunday, the striker said: "Grant used to look down on me. It was as though he felt I should be grateful and not ask for anything. The pretext for this was I had been brought in from Bolton."
Anelka said his treatment at the hands of Grant knocked his confidence to the extent he knew he was going to miss the decisive penalty in the 2008 Champions League final against Manchester United.
"I set great store by emotions and Grant did not show great confidence in me," said the Frenchman.
"In the 2008 Champions League final against Manchester United, Grant threw me on as a sub without giving me any warning.
"In the end I messed up the very last penalty in the shootout, which Edwin van der Sar pushed away. It is sad to say but I knew I was going to miss my kick."
