On-loan Spireites defender Tom Anderson has impressed in his time at the Proact, but had a challenging afternoon in the 4-1 loss to Walsall on Saturday.
A slice from the centre-back resulted in the own goal that drew the Saddlers level in the first half, while in the second period a mis-control gave opposition striker Jordy Hiwula the chance to score the visitors' third.
Boss Danny Wilson came to the defence of Anderson, and knows the experience will serve him well in the future: "The first goal can happen to anyone, you can see that from the goal that we scored. It happens, and in the rest of his career Tom's going to do a few more like that.
"It was a good ball in, but we didn't get to the first ball when it came in in the first place, that concerned me more than anything and that cost us.
"For the second one it was a silly ball back to him and he had a striker breathing down his neck, he's obviously taken his eye off the ball and that can happen.
"I'm not going to stand here and say it's Tom's fault because it's certainly not. It's all a learning process for him and a welcome to the real world."
Speaking before Saturday's game, the Chesterfield manager had spoken of the impact the 22-year-old Burnley man has made on his side's defence.
“The challenge that was in front of him when he came to us was playing league football," said Wilson. "I know he was at Carlisle but that was League Two, he’s stepped up a league and he’s found it easy.
“He’s so adaptable and has been terrific for us. What can you say? Nobody notices him because it’s just been so seamless with what he’s been doing.
“He has made a big, big difference to us at the back that's for sure. He’s played very well and I’m hoping he can continue with the progress he’s made. Tom’s been great for us.”
