On this day in 2004, Juninho scored at Highbury as Boro put one little fella-sized foot in the Carling Cup final.
Boro had beaten Everton and the Gunners' North London neighbours Spurs to reach the last four of the contest, but Arsenal presented the toughest challenge yet for Steve McClaren's side.
In the midst of their 'Invincibles' season, Arsene Wenger's men were a formidable force - yet to lose in any domestic competition that season.
But plucky Boro would change that in the first of this two-legged affair, thanks to a solitary goal from our Brazilian number 10.
