The attacking trio were all absent from the Eagles' 2-0 win over Doncaster Rovers earlier in the week – with Nketiah also absent against Manchester United the previous week – but Glasner is expecting to have all three available at Selhurst Park on Saturday.
"There are no new issues, and all three are back," the manager confirmed in his pre-match press conference. "All three trained and are available tomorrow."
Adam Wharton made his first start since October at the Eco-Power Stadium earlier this week, completing 62 minutes – and his manager confirmed he feels the midfielder is now fit enough to start.
"It was surprising he could play 60 minutes," Glasner smiled. "Even then he said, ‘oh, come on, I’d like to play more!'
"He did well. He trained the whole week – no reaction on the load – and he had a good week again. I think he’s ready and now, with the other players back, it’s maybe tough – but it's the best situation you can have as manager.
"We have him, Will Hughes and Jeff Lerma in midfield. We have several options in our front three, the same as our wing-backs. We have a good situation, of course, and we want to keep this for the next three months."
Ben Chilwell came off the bench to make his debut for the club against Doncaster, and Glasner said of the loanee: "For me, every player who is in the squad has to be able to start, otherwise it makes no sense.
"Ben is ready to start. That doesn’t meant that he starts [against Everton] because also T [Tyrick Mitchell] did well – it’s now to find the best mix.
"We’ve been quite successful the last weeks and we want to stay consistent, but it’s good to have options. There will be busier periods in the next months; now we have one week until Fulham [away], but then we have the next three-game week.
"Every player wants to play football, that's why they have this job and why they are doing it. Of course it was good for Ben to be back in team training, to be back in a game, because [he was] always training individually [at Chelsea] and a lot of time in the gym, and then you have to become a weightlifter and not a football player!
"He's a football player, he's a great football player, and that's why I think he also enjoyed it."
