Head coach Carlos Carvalhal felt Sheffield Wednesday's 3-0 League Cup win over Arsenal was a result of a perfect 'plan'.
Wednesday inflicted the largest defeat on Arsenal by a lower-division side since 1959 thanks to goals from Ross Wallace, Lucas Joao and Sam Hutchinson.
The result was no smash-and-grab effort from the Championship side, with Arsene Wenger's men fashioning just a couple of openings throughout the game.
And Carvalhal felt Wednesday's preparation allowed them to shut their opponents down.
He told Sky Sports: "We had a plan and our players were amazing. Everything belongs to the players.
"The followed the plan and we created a fantastic victory."
He added: "We understood two or three players weren't there, but we had players missing too.
"They have a great squad and a lot of those players are internationals from different countries."
The triumph secured Wednesday's spot in the quarter-final, although Carvalhal is refusing to look too far ahead.
He said: "We have to take it step by step. We are in the Championship and will be the outsiders in this competition."
