Mikel Arteta's outlandish team talk involving a light bulb has been revealed by the All or Nothing: Arsenal show.
The last two episodes of the highly anticipated fly-on-the-wall Amazon documentary are released on Tuesday.
And fans will be keen to see Gunners manager Arteta's bizarre motivational techniques, as he urged his players in a pre-game speech to create 'energy' and 'electricity' as he held a lit light bulb up to them.
Arsenal went on to lose that match, in early April, 2-1 against Brighton, the second in a run of three successive losses which would eventually cost them Champions League football at the expense of bitter rivals Tottenham.
