Having been an admirer of the FA Cup prior to his arrival at Hillsborough, Carlos Carvalhal is all too aware of the tradition of this competition.
In-form Owls – who are unbeaten in 2016 – are favourites to emerge triumphant over Shrewsbury and progress into the fifth round.
But the game will be anything but straightforward, according to the head coach.
He said: “This competition has a very big tradition because surprises can appear around the corner so we must be with full attention.
“We know we will have a good base of support in the stadium so we expect to do a good game and are completely focused.
“This is a cup game and we know these kind of games are not easy.
“These opponents beat Cardiff in the previous round, they gave a lot of difficulties to Chelsea in the Capital One Cup last season.
“Chelsea won 2-1 but was a very tough game.”
In the build-up to the fourth round cup-tie, Carlos says the players have enjoyed a productive week on the training pitch.
After defeating Fulham in the previous round earlier this month, Shrewsbury are next-up and he added:
“We have had a week to train with the players and we are happy about that.
“All the players are training very well, in very good shape with a lot of enthusiasm.”
