VIEWS FROM THE DRESSING ROOM
Barnet manager Lawrie Sanchez told BBC London 94.9:
"I said to the players at the beginning of pre-season: I saw you celebrating on the field at the end of the season but really you were celebrating avoiding failure.
"Let's celebrate something more than that.
"We have had a good pre-season, we've been undefeated in our pre-season games and team spirit is building."
