Three players were missing for the Reds' win over Colchester last Friday, having served on the international stage, with Paul Digby, Marcello Trotta and Ryan Williams returning to Oakwell this week, but there are no fresh injury concerns.
"I think we’ll have a similar squad,” said Wilson. “We’re still waiting for the international boys - to see whether they’ll be fit or not - particularly after the games and travelling they’ve had. So we’ll assess that in the morning.
“I would expect them to be in the country today. Ryan’s had a long journey to China. We’ll see them tomorrow and get a feel for them tomorrow.
“In an ideal world we’d like to kept Ryan on. He’s contributed greatly for the team with the last six or seven games he’s played.
“If he keeps progressing like he is, I see no reason why we wouldn’t want to keep him for longer.
“It’s very important for us, we want to know where we are and not have it sprung on us in January. We’re planning for the longer-term.
“They are conversations we need to have and are having at the moment.
“The little bit of a break Joe (Dudgeon) had out of the first team, for two or three games, he’s come back really on top of his game again. We think it was the right thing to do at the time and he’s got that energy back again. If he continues like that then Joe will be in the equation as well.
“The only thing that I’m hearing from where I am is that whilst they’re here, they want to play for us, which is great. There are obviously bigger pictures for one or two of the players and Marcello or whatever his ambitions are, I don’t know. But the thing that satisfies me the most is that he wanted to come to us."
The Reds boss has warned of Chesterfield's capabilities despite being a poor run of form, with just one win in eight games.
“Chesterfield are going very well," added Wilson. "I know, looking at he results, you’ll take an opinion on that but I’ve watched them two or three times now and they’re a good side. They’re a very good side and they’ve been particularly unlucky in the game I went to against Swindon. For 20-25 minutes at the start of that game, they were exceptional.
“It was enough for me to see that they’ll be a real, real handful for us - particularly at the Proact Stadium.
“We’ll approach it like we did all the games in recent times but there’s that added incentive that it’s sort of a derby game, if you like.
“The fans that we’re taking is absolutely phenomenal so, in that respect, we want to put a show on for them as well.
“They’ve had a great deal of success in the past few seasons with Paul in charge there and they do play in a certain way. If they get on top of you, it’s very difficult to hold them back.
“By all accounts they played very well at Crewe last week but didn’t get the win.
“But, when you’re not scoring goals and not winning games, you take a dent in confidence. We’ve got to go into that arena with as much confidence as we can take and, hopefully, dent their confidence even more.
“We’ll see what style or complexion the game takes. We go into it in good form and we’ve got areas where we can cause them problems. We’ll be going there to win the game. Whatever happens during the game, we’ll have to adjust to that but we’ll be going there to win.
“It possibly might be an open game, I really don’t know. But we’ve got to make sure that we defend and we defend properly."
