Former Leicester winger Anthony Knockaert has hit out at Watford fans in a furious rant on social media.
Knockaert was livid after constantly being reminded of his penalty miss against Watford in the dramatic 2013 Championship play-off semi-final.
The sides were level at 2-2 on aggregate when Knockaert stepped up to take a penalty, which was saved by Watford goalkeeper Manuel Almunia.
In one of the most memorable footballing moments of recent years Watford then went down the other end of the pitch, with Jonathan Hogg setting up Troy Deeney, who scored a dramatic winner.
Knockaert has now responded to Watford fans who have frequently messaged him as he reminded them that they were beaten by Crystal Palace in the play-off final.
