Nicolas Anelka vs. Liverpool
Having enjoyed a prolific loan spell at Anfield, it was some surprise when Reds manager Gerard Houllier turned down the opportunity to sign now controversial striker Nicolas Anelka, instead plumping for El-Hadji Diouf. Anelka moved to Manchester City instead and came back to haunt Houllier, scoring both goals for City in a 2-1 win at Anfield in 2003.
