However, Simon Grayson's side travel to Hillsborough in need of a win after slipping into the bottom three.
A promising run in the Capital One Cup may have helped the Owls build confidence, and Carvalhal was quick to praise his team for sticking to their gameplan after beating Newcastle United at St James' Park.
However, their narrow win over struggling Brentford may have prompted the Wednesday coach to consider delving into the transfer market for more attacking options.
At the back, Wednesday appear to be improving, having kept two clean sheets in their last four matches – at Newcastle and in the goalless draw against Bolton Wanderers.
However, the impending visit of Hull City to Hillsborough and a trip Queens Park Rangers later this month could put that defence under greater strain.

Preston North End
However, goals have been hard to come by so far, with North End having netted just six in the league this term - the worst record of any team in the division.
Admittedly, the loss of Beckford, who finished their last campaign on fire, will not have helped their cause. However, Garner's slump has also been a factor, with the 27-year-old yet to find the back of the net in the Championship.
Worse still, the Lilywhites have taken only two points from their last six games, with only MK Dons in a poorer run of form.

Garner's red card against Wolves should mean that summer signings Doyle and May lead the attack for the Lilywhites, having played as part of a front three recently.
North End's top scorer Johnson is expected to continue on the wing, but Bailey Wright's dismissal last weekend means that he will miss the trip to the Steel City.
However, Adam Reach should feature for the visitors after making his debut last weekend.
Meanwhile, Jeremy Helan starts a suspension following his sending-off in Wednesday's victory over Brentford.
Sheffield Wednesday possible starting lineup:
Westwood, Turner, Lees, Hutchinson, Matias, Nuhiu, Lee, Hunt, Wallace, Pudil, Bannan
Preston North End possible starting lineup:
Pickford; Woods, Vermijl, Clarke, Cunningham; Reach, Welsh, Browne, Johnson; May, Doyle
Head To Head
Wednesday's record against Preston is mixed, having lost 40 and won 39 of the 102 encounters between the clubs.
However, the Owls have had the better of recent meetings with North End, losing only one of the last seven. That defeat came courtesy of goals from Neil Mellor and Jon Parkin in a 2-0 triumph in October 2009.
Wednesday also won the last fixture between the sides back in March 2012 when the teams were playing in League One, with Gary Madine netting twice for the Yorkshiremen.

We say: Sheff Wed 2-1 Preston
While Doyle and ex-Wednesday forward May will have a point to prove after their summer transfers, the Owls' recent form, and Preston's lack of goals, suggests that the hosts might have too much for the Lilywhites on this occasion.
