Wolves recorded their first win under new manager Walter Zenga with a 2-1 League Cup win over Crawley Town.
Zenga's side needed a goal from Conor Coady to see them into the next round, with the midfielder starting the game in an unusual full-back role.

Joe Walsh had put Wolves in front after just seven minutes, before Crawley equalised through Enzio Boldewijn.
Zenga started new signing Joao Teixeira in midfield, after the Benfica loanee's impressive cameo appearance in the 2-2 draw with Rotherham United at the weekend.
Jon Dadi Bodvarsson was brought off the bench at half-time for Jed Wallace, while another new boy winger Helder Costa also came on after 45 minutes.
The early changes with the score at 1-1 at the break showed Zenga has a willingness to force the issue, and wants to make things happen rather than be reactive.
The substitutions appeared to help Wolves, with Bodvarsson effective up top, and the win will be a weight off their shoulders.
They need to follow this up with a Championship victory this weekend at home to Jaap Stam's Reading, but early on the signs are good.
Here is a look at Wolves' fans reactions to Zenga's tactics and approach...
Can see what zenga wants to do just watching Costa, tex and gudi. Press high and fast tempo. Time and more players needed. #wwfc— Stuart Polak (@stu_polak82) August 9, 2016
One of the biggest problems with Jackett was inability to change a game. Zenga not afraid to switch things early and it's working #wwfc— Mark Stefanyszyn (@m_stefanyszyn) August 9, 2016
Have to hand it to Zenga his substitutions won the game again. Costa second half and Dadi's nod back to Coady #wwfc— Danny O'Neil (@DannyONeil2) August 9, 2016
Refreshing how Zenga isn't afraid to shake things up and make subs/tactical changes early on. #wwfc— Paddy Day (@paddyday90) August 9, 2016
If we've learnt anything over the 1st 2 games it's that 4-4-2 suits us better. Let's hope Zenga has picked this up too! #wwfc— Adam Field (@AdzField) August 9, 2016
