Tisdale said: "I expected more to be honest. I don't think we did as well as we could have done.
"I think we could have performed better in the first half. I asked the players to play a certain way, but we didn't show enough energy, except for Liam Sercombe, who looked like he should have been playing for them.
"Maybe it's because we have had two games at the start of the season and we're not quite up and running yet.
"We improved in the second half and the substitutions gave us a lift, which is what I intended it to do.
"I was hoping we would have been a goal in it at that point, I wanted to be in a position where we had a chance, but at 2-0, I think it was just too much to ask for."
