The South Yorkshire outfit have climbed to fifth place in the league following a fantastic run that has seen them win four games on the bounce.
Rovers took the lead early in the second half before the Owls hit back and eventually won the game 2-1, and when Carvalhal spoke to Sky Sports, he hailed his side's resilience:
"It's not the first time we've been losing here at Hillsborough. We've played in this situation, which is very important. That's why we didn't disturb the team and we had the reaction and scored for 1-1."
Wednesday continue to display their never-say-die attitude, and they have now gained 12 points from losing positions at Hillsborough this term.
The former Besiktas manager went on to say how he decided to change his team, and tactics, following Craig Conway's dismissal for the visitors, whilst praising the influence of Spanish midfielder - Alex Lopez:
"After the red card, we changed the system because we wanted to create more problems for the organisation of the Blackburn defence. Alex Lopez controlled the game in that moment very well, from right to left. Everybody understood it was a question of when our team would score the second goal."
Next up for Carvalhal's side is a trip to 20th placed Bristol City, before back-to-back home games against Ipswich Town and MK Dons.
They will be hoping to keep up their fine run of form, as they look to further cement their position in the play-off places.
