Extra police provision was put in place in case sparks flew in this south London derby, but that was intended to ensure all was above board off the pitch, not on it. With just five and a half minutes on the clock, Roberts produced a horrendous tackle, resembling Harald Schumacher’s on Patrick Battiston at the 1982 World Cup. Roberts’ kung-fu kicked the ball away but followed through, studs up, onto Jean-Philippe Mateta’s face.
