Arsenal failed to follow the law of what Mikel Arteta described as the "jungle" of Anfield as his side ceded significant control in the Premier League title race in a thrilling draw at Liverpool.
The Gunners boss' attempts to familiarise his players with Anfield's hostile environment included making his players train with the strains of the Liverpool anthem 'You'll Never Walk Alone' as a backing track to training sessions last season.
That all went awry when Arteta got involved in a touchline spat with opposite number Jurgen Klopp with the scoreline goalless, Liverpool and Anfield then exploding in fury and Arsenal crashing to a 4-0 loss.
