Charlie Wakefield replaced Joe Rowley in the second half against Scunthorpe United and in doing so became the seventh youngest player to feature for the Spireites first team and the first who was born in the 21st century.
On the young duo, Stuckmann said: “With Joe you have seen in the last couple of weeks that he is a really good player and if he keeps working hard, which I think he will, then he will have a good career in the game, because he is a great character too.
“With Charlie as well, he has been training with us on a regular basis for two weeks now, and he has been doing really well.
“With young players like these two it is best to throw them in so that they get some experience and then hopefully they can build on that in the future.
“These two boys know that they will have to work hard and I am sure that all of the experienced players will help them.”
Monday’s 3-1 defeat to Scunthorpe confirmed Chesterfield’s relegation from the Sky Bet League One and the German stopper urged supporters to stick with them in these times.
Gary Caldwell’s side have just Charlton Athletic and Sheffield United left to play, and Stuckmann assured supporters that the team will keep fighting.
“We have to get our heads together and react in a positive manner to make sure that we finish the season off with two positive results.
“We have to leave our heart on the pitch next Saturday and we have to play and show some pride and just show everything we can. We have to make the fans want to come back next season.”
