Former Wrexham midfielder Waynne Phillips acknowledges that the club have enjoyed a successful season in the Championship – but that missing out on the play-offs would be a "disappointment".
Wrexham are sixth in the table and host fourth-placed Middlesbrough on Saturday (12:30 BST).
Victory for Wrexham would give them a play-off spot unless Hull City can claim victory by a bigger winning margin, while anything less could also open the door for Derby County to sneak into sixth place.
"There will be an element of disappointment if they don't make it into the top six," Phillips told BBC Radio Cymru's Dros Frecwast.
"They will have come so close having done so well for the majority of the season.
"I'm disappointed with how the season has finished for them – their worst run of the season has come at the most important time.
"But Middlesbrough have not been at their best in the last 10 games – if you look back to two months ago it looked like Middlesbrough were going up automatically.
"Things change in football – what counts now is not what has happened in 45 games this season but the 90 minutes tomorrow [Saturday] afternoon."
