5) Suarez to have a moment of madness
It tends to happen in the big games – will we see another crazy moment from Luis Suarez this weekend? The Uruguayan most recently bit Italy defender Giorgio Chiellini at the World Cup last summer (luckily for him, he’s missing this game through injury) in a decisive match in the group stages, following on from his bite on Chelsea’s Branislav Ivanovic. His verbal attack on Patrice Evra also came in the huge grudge match between Liverpool and Manchester United. So far at Barca he’s been a good boy, but could this occasion bring the worst out of him again?
