With a sold-out S6 expected on May 18, the home leg comes first of course and Darren Moore has a number of difficult selection decisions to make as they look to match-up and better the Posh.
Josh Windass looks set to play a part, Lee Gregory is expected back and there are calls to be made on Reece James, Michael Ihiekwe and Aden Flint. Where will Liam Palmer slot in? How attacking will the midfield line-up be?
Just a few of many questions - it’s a good position for the Owls to be in after weeks of injury scrambling.
What team will Wednesday plump for at London Road? We’ve had a stab.
5. RWB - Callum Paterson
With Palmer pulled into the back three, the next question is who would be best to deputise out wide. Jack Hunt is a sound option and got valuable minutes under his belt on Sunday, Dennis Adeniran has played there usefully. But we’ve gone for the hustle, bustle and physicality of Callum Paterson, who hasn’t played wide right for some time but has produced some of his best form there. Photo: Gareth Copley
6. CM - Will Vaulks
A sure-fire selection you’d think. Has grown and grown into his Wednesday shirt and is a fiercely important player - as important as anyone. Vital in terms of setting the tone both defensively and in possession. In the midfield we’ve plumped for, his performance must be on-point. Photo: George Wood
7. CM - Barry Bannan
Skipper of the ship and the most important figure in the squad. Stats out this week display just how classy a performer he is at this level. Based deeper in our midfield, he can do some damage with Josh Windass back in and creating havoc in front of him. | Getty Images
8. LWB - Marvin Johnson
A class act out wide; dependable going forward and increasingly so defensively, too. Is a getter of assists and causes problems for opposition defences. Another shoo-in. Photo: Rhianna Chadwick
