Anelka slams Portsmouth boss Grant over Chelsea treatment
Anelka says he spent six unhappy months under Grant in 2007-08.
In a new book published tomorrow, he even claims he missed the seventh and decisive penalty in the 2008 Champions League final as his confidence was so low.
Anelka writes: "I set great store by emotions and Grant did not show great confidence in me.
"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."
Grant has previously claimed Anelka, a £15m buy from Bolton, was brought in against his wishes in January 2008.
Anelka, played mostly out wide or as a sub by Grant, adds: "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."
