Bannan has said that he is enjoying playing with fellow midfielder Pelupessy, who joined Wednesday from Heracles Almelo in the January transfer window.
The 28-year-old midfielder told Sky Sports: "Joey has been brilliant since he came over from Holland. Sometimes people take time to adapt to different leagues but Joey has come in and fitted in straightaway.
“I am enjoying my partnership with him. He is the complete opposite of me in terms of how we play so we are good for each other.
“It allows me to express myself further forward and he does the horrible bits that nobody likes to do.
“Joey is the perfect foil. I can't forget about defending but it allows me to focus on what I want to do which is score goals and make goals.”
Pelupessy has been superb for Wednesday so far in his career and has established himself as a key figure for the Owls.
The 25-year-old midfielder has played in all six of Wednesday’s Championship matches so far this campaign.
