VIEWS FROM THE DRESSING ROOM
Aldershot Town manager Andy Scott told BBC Surrey:
"We made the pitch too big, we didn't squeeze them, we didn't win enough second balls and we were too deep defensively. we gave the opportunities to the other team and gave them the impetus.
"We didn't look like we had a cutting edge in the game, we didn't look like we could create too much and we looked toothless to be honest.
"We didn't use our knowledge, experience to start the game well enough and that's the difference. We need to address out starts and we can do it and we've got to have everyone in the team to show their effort."
