Phil Bardsley believes the Clarets have added another useful weapon to their tactical armoury as they plan another capital raid.
Burnley return to North London for the second time in eight days when they face Arsenal at the Emirates Stadium on Saturday.
Sean Dyche’s men returned from Wembley empty-handed last weekend with late goal giving Tottenham a 1-0 win.
But the Clarets unveiled a new-look five-man defence which kept the title-challengers at bay until injury time.
And Bardsley – who lined up alongside three central defenders – has faith in the system working again if that’s the way Dyche plans to go against the fifth-placed Gunners.
