Port Vale were condemned to defeat on Saturday afternoon at the hands of Carlisle United, and the boss has expressed his disappointment following the tie.
The first half of the game was full of positives against the in-form Cumbrians. Vale enjoyed the majority of possession and calved open a handful of opportunites to put themselves ahead, though just lacked that cutting edge in front of goal to affect the scoreline.
However, with just five minutes to play in the first period of the game, Ricky Miller was shown a straight red card for a late challenge on Carlisle full-back, Danny Grainger. With a new game plan, Vale put everything on the line in the second half and looked good to collect a point at Vale Park.
Though, with just over ten minutes to play, a scrappy goal that took a double deflection found it's way past Scott Brown and into the Vale net. The boss admitted the sending off was a huge turning point in the game.
He said: "It's hard to take. You're hoping to win the game at the start, then when you go down to 10 men, hopefully you can get a goal but if not, you'll take a point.
"To concede the goal in the way we did with an own goal and a double defection, unfortunately it sums up the way things are going. It's very disappointing and there's not a lot I can say, just how really disappointed we are."
Following the loss, the boss has praised the performance of Mark Harris having made his debut for The Valiants as a first-half substitute.
With the dismissal of Ricky, Aspin decided to bring on the new-boy in search of a goal and the debutant impressed with a number of good touches after his arrival.
The boss has claimed that including Harris, the entire squad's work ethic was spot on for the full 90 minutes, saying there is no criticism for any of the players.
He said: "Anyone you bring in, you're always hoping they can do well. He's got ability; you're not going to get any players able to come into a club at this level and be a Ronaldo or a Messi.
"But he worked hard, he showed that he knew what he was doing up there. It would've been much better if we could've been bringing him on where we were leading in the game and it was opening up.
"I have no problem with the way the players went about the game today. No problem with the attitude; I thought they worked hard."
