Leeds’ disappointing pre-season ended as they once again failed to record a victory, losing to a penalty shoot-out to Aston Villa and then going down 2-0 to Eircom League leaders Shelbourne.
"Football sometimes is about attitude and certainly as a team the attitude wasn’t right," said Reid on leedsunited.com.
"We had a chat before we went out about Villa being a Premiership side and being up for it, but this was a different type of game where we had to go out and match them and then play our football.
"They got a goal against us and we just fell apart, I know it’s a team that we made a lot of changes to. There was enough experience out there to deal with it, but we didn’t do that.
"I left a few experienced players who should be in the team against Newcastle out, but it still wasn’t good enough."
Reid also felt the players had not done the Leeds fans justice, who had travelled not only from England, but all over Ireland to watch the team in action.
He added: "When I look at us when we concede a goal, heads go down instead of getting a reaction.
"Against Villa we fought back and showed a lot of character, but on Sunday it just looked as if it was too hot out there and the attitude wasn’t right.
"The players did not do themselves justice and the crowd justice because there were a lot of fans here who paid good money to be here."
The most dismal aspect of Leeds' pre-season was a total lack of creative flair, and with the big kick-off against Newcastle next Sunday looming large, the side cries out for a creative midfield player who can score goals.
Someone like Lee Bowyer or Harry Kewell. Oh damn!
We had them but we sold them didn't we?
